880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder <p>Apache is configured by placing <a href="mod/directives.html">directives</a> in plain text
880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder configuration files. The main configuration file is usually called
880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder <code>httpd.conf</code>. The location of this file is set at
880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder compile-time, but may be overridden with the <code>-f</code>
880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder command line flag. In addition, other configuration files may be
880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder added using the <code class="directive"><a href="/mod/core.html#include">Include</a></code>
880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder directive, and wildcards can be used to include many configuration
880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder files. Any directive may be placed in any of these configuration
880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder files. Changes to the main configuration files are only
880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder recognized by Apache when it is started or restarted.</p>
880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder <p>The server also reads a file containing mime document types;
880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder the filename is set by the <code class="directive"><a href="/mod/mod_mime.html#typesconfig">TypesConfig</a></code> directive,
880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder and is <code>mime.types</code> by default.</p>

880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder <p>Apache configuration files contain one directive per line.
880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder The back-slash "\" may be used as the last character on a line
880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder to indicate that the directive continues onto the next line.
880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder There must be no other characters or white space between the
880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder back-slash and the end of the line.</p>
880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder <p>Directives in the configuration files are case-insensitive,
880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder but arguments to directives are often case sensitive. Lines
880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder that begin with the hash character "#" are considered
880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder comments, and are ignored. Comments may <strong>not</strong> be
880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder included on a line after a configuration directive. Blank lines
880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder and white space occurring before a directive are ignored, so
880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder you may indent directives for clarity.</p>
880945fae9c3f61341f1cd94439c802b7a0af194Jonathan von Schroeder <p>You can check your configuration files for syntax errors
fee6e355c164d9248e0512436812a476ad0c2e99Jonathan von Schroeder without starting the server by using <code>apachectl
