</div>

    <p>
      This is an index of the directives that are allowed in .htaccess files for
      various <code class="directive"><a href="../mod/core.html#allowoverride">AllowOverride</a></code> settings,
      organized by class. Its intended purpose is to help server administrators
      verify the privileges they're granting to .htaccess users. For an overview
      of how .htaccess works, see the
      <a href="../howto/htaccess.html">.htaccess tutorial</a>.
    </p>

    <p>
      To determine the set of directives that your server configuration allows
      .htaccess users to use:
    </p>

    <ol>
      <li>Start with the set of directives in the <code>AllowOverrideList</code>
      for the directory in question. (By default, this is set to
      <code>None</code>.)</li>
      <li>Find the <code>AllowOverride</code> setting for the directory in
      question. (By default, it is set to <code>None</code>.) There are two
      special cases:
        <ol>
          <li>If your <code>AllowOverride</code> setting is <code>All</code>,
          add every directive listed on this page to the list.</li>
          <li>If your <code>AllowOverride</code> setting is <code>None</code>,
          you're done. Only the directives in the <code>AllowOverrideList</code>
          (if any) will be allowed.</li>
        </ol>
      </li>
      <li>For each override class listed in <code>AllowOverride</code>, look up
      the corresponding set of directives below and add them to the list.</li>
      <li>Finally, add the set of directives that is always allowed in
      .htaccess (these are listed in the
      <a href="#override-all">All section</a>, below).</li>
    </ol>

    <p>
      Several of the override classes are quite powerful and give .htaccess
      users a large amount of control over the server. For a stricter approach,
      set <code>AllowOverride None</code> and use
      <code class="directive"><a href="../mod/core.html#allowoverridelist">AllowOverrideList</a></code> to specify the
      exact list of directives that .htaccess users are allowed to use.
