+
+ <p>Apache HTTP Server is configured by placing <a href="mod/directives.html">directives</a> in plain text
+ configuration files. The main configuration file is usually called
+ <code>httpd.conf</code>. The location of this file is set at
+ compile-time, but may be overridden with the <code>-f</code>
+ command line flag. In addition, other configuration files may be
+ added using the <code class="directive"><a href="./mod/core.html#include">Include</a></code>
+ directive, and wildcards can be used to include many configuration
+ files. Any directive may be placed in any of these configuration
+ files. Changes to the main configuration files are only
+ recognized by httpd when it is started or restarted.</p>
+
+ <p>The server also reads a file containing mime document types;
+ the filename is set by the <code class="directive"><a href="./mod/mod_mime.html#typesconfig">TypesConfig</a></code> directive,
+ and is <code>mime.types</code> by default.</p>
+ </div><div class="top"><a href="#page-header"><img alt="top" src="./images/up.gif" /></a></div>
+<div class="section">
+<h2><a name="syntax" id="syntax">Syntax of the Configuration Files</a></h2>
+
+
+ <p>httpd configuration files contain one directive per line.
+ The backslash "\" may be used as the last character on a line
+ to indicate that the directive continues onto the next line.
+ There must be no other characters or white space between the
+ backslash and the end of the line.</p>
+
+ <p>Arguments to directives are separated by whitespace. If an
+ argument contains spaces, you must enclose that argument in quotes.</p>
+
+ <p>Directives in the configuration files are case-insensitive,
+ but arguments to directives are often case sensitive. Lines
+ that begin with the hash character "#" are considered
+ comments, and are ignored. Comments may <strong>not</strong> be
+ included on the same line as a configuration directive.
+ White space occurring before a directive is ignored, so
+ you may indent directives for clarity. Blank lines are also ignored.</p>
+
+ <p>The values of variables defined with the <code class="directive"><a href="./mod/core.html#define">Define</a></code> of or shell environment variables can
+ be used in configuration file lines using the syntax <code>${VAR}</code>.
+ If "VAR" is the name of a valid variable, the value of that variable is
+ substituted into that spot in the configuration file line, and processing
+ continues as if that text were found directly in the configuration file.
+ Variables defined with <code class="directive"><a href="./mod/core.html#define">Define</a></code> take
+ precedence over shell environment variables.
+ If the "VAR" variable is not found, the characters <code>${VAR}</code>
+ are left unchanged, and a warning is logged.
+ Variable names may not contain colon ":" characters, to avoid clashes with
+ <code class="directive"><a href="./mod/mod_rewrite.html#rewritemap">RewriteMap</a></code>'s syntax.</p>
+
+ <p>Only shell environment variables defined before the server is started
+ can be used in expansions. Environment variables defined in the
+ configuration file itself, for example with <code class="directive"><a href="./mod/mod_env.html#setenv">SetEnv</a></code>, take effect too late to be used for
+ expansions in the configuration file.</p>
+
+ <p>The maximum length of a line in normal configuration files, after
+ variable substitution and joining any continued lines, is approximately
+ 16 MiB. In <a href="configuring.html#htaccess">.htaccess files</a>, the
+ maximum length is 8190 characters.</p>
+
+ <p>You can check your configuration files for syntax errors
+ without starting the server by using <code>apachectl
+ configtest</code> or the <code>-t</code> command line
+ option.</p>
+
+ <p>You can use <code class="module"><a href="./mod/mod_info.html">mod_info</a></code>'s <code>-DDUMP_CONFIG</code> to
+ dump the configuration with all included files and environment
+ variables resolved and all comments and non-matching
+ <code class="directive"><a href="./mod/core.html#ifdefine">&lt;IfDefine&gt;</a></code> and
+ <code class="directive"><a href="./mod/core.html#ifmodule">&lt;IfModule&gt;</a></code> sections
+ removed. However, the output does not reflect the merging or overriding
+ that may happen for repeated directives.</p>

+
+ <p>httpd is a modular server. This implies that only the most
+ basic functionality is included in the core server. Extended
+ features are available through <a href="mod/">modules</a> which can be loaded
+ into httpd. By default, a <a href="mod/module-dict.html#Status">base</a> set of modules is
+ included in the server at compile-time. If the server is
+ compiled to use <a href="dso.html">dynamically loaded</a>
+ modules, then modules can be compiled separately and added at
+ any time using the <code class="directive"><a href="./mod/mod_so.html#loadmodule">LoadModule</a></code>
+ directive.
+ Otherwise, httpd must be recompiled to add or remove modules.
+ Configuration directives may be included conditional on a
+ presence of a particular module by enclosing them in an <code class="directive"><a href="./mod/core.html#ifmodule">&lt;IfModule&gt;</a></code> block. However,
+ <code class="directive">&lt;IfModule&gt;</code> blocks are not
+ required, and in some cases may mask the fact that you're missing an
+ important module.</p>
+
+ <p>To see which modules are currently compiled into the server,
+ you can use the <code>-l</code> command line option. You can also
+ see what modules are loaded dynamically using the <code>-M</code>
+ command line option.</p>

+
+ <p>Directives placed in the main configuration files apply to
+ the entire server. If you wish to change the configuration for
+ only a part of the server, you can scope your directives by
+ placing them in <code class="directive"><a href="./mod/core.html#directory">&lt;Directory&gt;</a></code>, <code class="directive"><a href="./mod/core.html#directorymatch">&lt;DirectoryMatch&gt;</a></code>, <code class="directive"><a href="./mod/core.html#files">&lt;Files&gt;</a></code>, <code class="directive"><a href="./mod/core.html#filesmatch">&lt;FilesMatch&gt;</a></code>, <code class="directive"><a href="./mod/core.html#location">&lt;Location&gt;</a></code>, and <code class="directive"><a href="./mod/core.html#locationmatch">&lt;LocationMatch&gt;</a></code>
+ sections. These sections limit the application of the
+ directives which they enclose to particular filesystem
+ locations or URLs. They can also be nested, allowing for very
+ fine grained configuration.</p>
+
+ <p>httpd has the capability to serve many different websites
+ simultaneously. This is called <a href="vhosts/">Virtual
+ Hosting</a>. Directives can also be scoped by placing them
+ inside <code class="directive"><a href="./mod/core.html#virtualhost">&lt;VirtualHost&gt;</a></code>
+ sections, so that they will only apply to requests for a
+ particular website.</p>
+
+ <p>Although most directives can be placed in any of these
+ sections, some directives do not make sense in some contexts.
+ For example, directives controlling process creation can only
+ be placed in the main server context. To find which directives
+ can be placed in which sections, check the <a href="mod/directive-dict.html#Context">Context</a> of the
+ directive. For further information, we provide details on <a href="sections.html">How Directory, Location and Files sections
+ work</a>.</p>

+
+ <p>httpd allows for decentralized management of configuration
+ via special files placed inside the web tree. The special files
+ are usually called <code>.htaccess</code>, but any name can be
+ specified in the <code class="directive"><a href="./mod/core.html#accessfilename">AccessFileName</a></code>
+ directive. Directives placed in <code>.htaccess</code> files
+ apply to the directory where you place the file, and all
+ sub-directories. The <code>.htaccess</code> files follow the
+ same syntax as the main configuration files. Since
+ <code>.htaccess</code> files are read on every request, changes
+ made in these files take immediate effect.</p>
+
+ <p>To find which directives can be placed in
+ <code>.htaccess</code> files, check the <a href="mod/directive-dict.html#Context">Context</a> of the
+ directive. The server administrator further controls what
+ directives may be placed in <code>.htaccess</code> files by
+ configuring the <code class="directive"><a href="./mod/core.html#allowoverride">AllowOverride</a></code>
+ directive in the main configuration files.</p>
+
+ <p>For more information on <code>.htaccess</code> files, see
+ the <a href="howto/htaccess.html">.htaccess tutorial</a>.</p>
