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> </div> <div id="quickview"><h3 class="directives">Directives</h3> <ul id="toc"> <li><img alt="" src="../images/down.gif" /> <a href="#directoryindex">DirectoryIndex</a></li> <li><img alt="" src="../images/down.gif" /> <a href="#directoryslash">DirectorySlash</a></li> </ul> </div> <div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div> <div class="directive-section"><h2><a name="DirectoryIndex" id="DirectoryIndex">DirectoryIndex</a> <a name="directoryindex" id="directoryindex">Directive</a></h2> <table class="directive"> <tr><th><a href="directive-dict.html#Description">Description:</a></th><td>List of resources to look for when the client requests a directory</td></tr> <tr><th><a href="directive-dict.html#Syntax">Syntax:</a></th><td><code>DirectoryIndex <var>local-url</var> [<var>local-url</var>] ...</code></td></tr> <tr><th><a href="directive-dict.html#Default">Default:</a></th><td><code>DirectoryIndex index.html</code></td></tr> <tr><th><a href="directive-dict.html#Context">Context:</a></th><td>server config, virtual host, directory, .htaccess</td></tr> <tr><th><a href="directive-dict.html#Override">Override:</a></th><td>Indexes</td></tr> <tr><th><a href="directive-dict.html#Status">Status:</a></th><td>Base</td></tr> <tr><th><a href="directive-dict.html#Module">Module:</a></th><td>mod_dir</td></tr> </table> <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 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> </div> <div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div> <div class="directive-section"><h2><a name="DirectorySlash" id="DirectorySlash">DirectorySlash</a> <a name="directoryslash" id="directoryslash">Directive</a></h2> <table class="directive"> <tr><th><a href="directive-dict.html#Description">Description:</a></th><td>Toggle trailing slash redirects on or off</td></tr> <tr><th><a href="directive-dict.html#Syntax">Syntax:</a></th><td><code>DirectorySlash On|Off</code></td></tr> <tr><th><a href="directive-dict.html#Default">Default:</a></th><td><code>DirectorySlash On</code></td></tr> <tr><th><a href="directive-dict.html#Context">Context:</a></th><td>server config, virtual host, directory, .htaccess</td></tr> <tr><th><a href="directive-dict.html#Override">Override:</a></th><td>Indexes</td></tr> <tr><th><a href="directive-dict.html#Status">Status:</a></th><td>Base</td></tr> <tr><th><a href="directive-dict.html#Module">Module:</a></th><td>mod_dir</td></tr> <tr><th><a href="directive-dict.html#Compatibility">Compatibility:</a></th><td>Available in version 2.0.51 and later</td></tr> </table> <p>The <code class="directive">DirectorySlash</code> directive determines, whether <code class="module"><a href="../mod/mod_dir.html">mod_dir</a></code> should fixup URLs pointing to a directory or not.</p> <p>Typically if a user requests a resource without a trailing slash, which points to a directory, <code class="module"><a href="../mod/mod_dir.html">mod_dir</a></code> redirects him to the same ressource, but <em>with</em> trailing slash for some good reasons:</p> <ul> <li>The user is finally requesting the canonical URL of the resource</li> <li><code class="module"><a href="../mod/mod_autoindex.html">mod_autoindex</a></code> works correctly. Since it doesn't emit the path in the link, it would point to the wrong path.</li> <li><code class="directive"><a href="#directoryindex">DirectoryIndex</a></code> will be evaluated <em>only</em> for directories requested with trailing slash.</li> <li>Relative URL references inside html pages will work correctly.</li> </ul> <p>Well, if you don't want this effect <em>and</em> the reasons above don't apply to you, you can turn off the redirect with:</p> <div class="example"><p><code> # see security warning below!<br /> <Location /some/path><br /> <span class="indent"> DirectorySlash Off<br /> SetHandler some-handler<br /> </span> </Location> </code></p></div> <div class="warning"><h3>Security Warning</h3> <p>Turning off the trailing slash redirect may result in an information disclosure. Consider a situation where <code class="module"><a href="../mod/mod_autoindex.html">mod_autoindex</a></code> is active (<code>Options +Indexes</code>) and <code class="directive"><a href="#directoryindex">DirectoryIndex</a></code> is set to a valid resource (say, <code>index.html</code>) and there's no other special handler defined for that URL. In this case a request with a trailing slash would show the <code>index.html</code> file. <strong>But a request without trailing slash would list the directory contents</strong>.</p> </div> </div> </div> <div class="bottomlang"> <p><span>Available Languages: </span><a href="../en/mod/mod_dir.html" title="English"> en </a> | <a href="../ja/mod/mod_dir.html" hreflang="ja" rel="alternate" title="Japanese"> ja </a> | <a href="../ko/mod/mod_dir.html" hreflang="ko" rel="alternate" title="Korean"> ko </a></p> </div><div id="footer"> <p class="apache">Copyright 1999-2004 The Apache Software Foundation.<br />Licensed under the <a href="http://www.apache.org/licenses/LICENSE-2.0">Apache License, Version 2.0</a>.</p> <p class="menu"><a href="../mod/">Modules</a> | <a href="../mod/directives.html">Directives</a> | <a href="../faq/">FAQ</a> | <a href="../glossary.html">Glossary</a> | <a href="../sitemap.html">Sitemap</a></p></div> </body></html>
