<h3>Summary</h3>

    <p>The index of a directory can come from one of two sources:</p>

    <ul>
      <li>A file written by the user, typically called
      <code>index.html</code>. The <code class="directive"><a href="#directoryindex">DirectoryIndex</a></code> directive sets the
      name of this file. This is controlled by
      <code class="module"><a href="../mod/mod_dir.html">mod_dir</a></code>.</li>

      <li>Otherwise, a listing generated by the server. This is
      provided by <code class="module"><a href="../mod/mod_autoindex.html">mod_autoindex</a></code>.</li>
    </ul>
    <p>The two functions are separated so that you can completely
    remove (or replace) automatic index generation should you want
    to.</p> 

    <p>A "trailing slash" redirect is issued when the server
    receives a request for a URL
    <code>http://servername/foo/dirname</code> where
    <code>dirname</code> is a directory. Directories require a
    trailing slash, so <code class="module"><a href="../mod/mod_dir.html">mod_dir</a></code> issues a redirect to
    <code>http://servername/foo/dirname/</code>.</p>

    <p>The <code class="directive">DirectoryIndex</code> directive sets the
    list of resources to look for, when the client requests an index
    of the directory by specifying a / at the end of the a directory
    name.  <var>Local-url</var> is the (%-encoded) URL of a document on
    the server relative to the requested directory; it is usually the
    name of a file in the directory. Several URLs may be given, in
    which case the server will return the first one that it finds.  If
    none of the resources exist and the <code>Indexes</code> option is
    set, the server will generate its own listing of the
    directory.</p>

    <div class="example"><h3>Example</h3><p><code>
      DirectoryIndex index.html
    </code></p></div>

    <p>then a request for <code>http://myserver/docs/</code> would
    return <code>http://myserver/docs/index.html</code> if it
    exists, or would list the directory if it did not.</p>

    <p>Note that the documents do not need to be relative to the
    directory;</p>

    <div class="example"><p><code>
      DirectoryIndex index.html index.txt  /cgi-bin/index.pl
    </code></p></div>

    <p>would cause the CGI script <code>/cgi-bin/index.pl</code> to be
    executed if neither <code>index.html</code> or <code>index.txt</code>
    existed in a directory.</p>
