    directive is legal. It's a comma-separated list of one or more
    of the following values:</p>

    <dl>
      <dt>server config</dt>

      <dd>This means that the directive may be used in the server
      configuration files (<em>e.g.</em>, <code>httpd.conf</code>), but
      <strong>not</strong> within any
      <code class="directive"><a href="../mod/core.html#virtualhost">&lt;VirtualHost&gt;</a></code>
      or <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code>
      containers. It is not allowed in <code>.htaccess</code> files
      at all.</dd>

      <dt>virtual host</dt>

      <dd>This context means that the directive may appear inside
      <code class="directive"><a href="../mod/core.html#virtualhost">&lt;VirtualHost&gt;</a></code>
      containers in the server
      configuration files.</dd>

      <dt>directory</dt>

      <dd>A directive marked as being valid in this context may be
      used inside <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&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#files">&lt;Files&gt;</a></code>
      containers in the server configuration files, subject to the
      restrictions outlined in <a href="../sections.html">How
      Directory, Location and Files sections work</a>.</dd>

      <dt>.htaccess</dt>

      <dd>If a directive is valid in this context, it means that it
      can appear inside <em>per</em>-directory
      <code>.htaccess</code> files. It may not be processed, though
      depending upon the <a href="#Override">overrides</a> currently active.</dd>
    </dl>

    <p>The directive is <em>only</em> allowed within the designated
    context; if you try to use it elsewhere, you'll get a
    configuration error that will either prevent the server from
    handling requests in that context correctly, or will keep the
    server from operating at all -- <em>i.e.</em>, the server won't
    even start.</p>

    <p>The valid locations for the directive are actually the
    result of a Boolean OR of all of the listed contexts. In other
    words, a directive that is marked as being valid in
    "<code>server config, .htaccess</code>" can be used in the
    <code>httpd.conf</code> file and in <code>.htaccess</code>
    files, but not within any <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code> or
    <code class="directive"><a href="../mod/core.html#virtualhost">&lt;VirtualHost&gt;</a></code>
    containers.</p>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="Override" id="Override">Override</a></h2>

    <p>This directive attribute indicates which configuration
    override must be active in order for the directive to be
    processed when it appears in a <code>.htaccess</code> file. If
    the directive's <a href="#Context">context</a>
    doesn't permit it to appear in <code>.htaccess</code> files,
    then no context will be listed.</p>

    <p>Overrides are activated by the <code class="directive"><a href="../mod/core.html#allowoverride">AllowOverride</a></code> directive, and apply
    to a particular scope (such as a directory) and all
    descendants, unless further modified by other
    <code class="directive"><a href="../mod/core.html#allowoverride">AllowOverride</a></code> directives at
    lower levels. The documentation for that directive also lists the
    possible override names available.</p>

<div class="section">
<h2><a name="Status" id="Status">Status</a></h2>

    <p>This indicates how tightly bound into the Apache Web server
    the directive is; in other words, you may need to recompile the
    server with an enhanced set of modules in order to gain access
    to the directive and its functionality. Possible values for
    this attribute are:</p>

    <dl>
      <dt>Core</dt>

      <dd>If a directive is listed as having "Core" status, that
      means it is part of the innermost portions of the Apache Web
      server, and is always available.</dd>

      <dt>MPM</dt>

      <dd>A directive labeled as having "MPM" status is provided by
      a <a href="../mpm.html">Multi-Processing Module</a>. This
      type of directive will be available if and only if you are
      using one of the MPMs listed on the <a href="#Module">Module</a> line of the directive
      definition.</dd>

      <dt>Base</dt>

      <dd>A directive labeled as having "Base" status is supported
      by one of the standard Apache modules which is compiled into
      the server by default, and is therefore normally available
      unless you've taken steps to remove the module from your
      configuration.</dd>

      <dt>Extension</dt>

      <dd>A directive with "Extension" status is provided by one of
      the modules included with the Apache server kit, but the
      module isn't normally compiled into the server. To enable the
      directive and its functionality, you will need to change the
      server build configuration files and re-compile Apache.</dd>

      <dt>Experimental</dt>

      <dd>"Experimental" status indicates that the directive is
      available as part of the Apache kit, but you're on your own
      if you try to use it. The directive is being documented for
      completeness, and is not necessarily supported. The module
      which provides the directive may or may not be compiled in by
      default; check the top of the page which describes the
      directive and its module to see if it remarks on the
      availability.</dd>
    </dl>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="Module" id="Module">Module</a></h2>

    <p>This quite simply lists the name of the source module which
    defines the directive.</p>

<div class="section">
<h2><a name="Compatibility" id="Compatibility">Compatibility</a></h2>

    <p>If the directive wasn't part of the original Apache version
    2 distribution, the version in which it was introduced should
    be listed here.  In addition, if the directive is available
    only on certain platforms, it will be noted here.</p>
