Generally, files + have implicit handlers, based on the file type. Normally, all + files are simply served by the server, but certain file types + are "handled" separately.</p> + + <p>Apache 1.1 adds the ability to use handlers explicitly. + Based on either filename extensions or on location, handlers + can be specified without relation to file type. This is + advantageous both because it is a more elegant solution, and + because it also allows for both a type <strong>and</strong> a + handler to be associated with a file. (See also <a href="mod/mod_mime.html#multipleext">Files with Multiple + Extensions</a>.)</p> + + <p>Handlers can either be built into the server or included in + a module, or they can be added with the <code class="directive"><a href="./mod/mod_actions.html#action">Action</a></code> directive. The + built-in handlers in the standard distribution are as + follows:</p> + + <ul> + <li><strong>default-handler</strong>: Send the file using the + <code>default_handler()</code>, which is the handler used by + default to handle static content. (core)</li> + + <li><strong>send-as-is</strong>: Send file with HTTP headers + as is. (<code class="module"><a href="./mod/mod_asis.html">mod_asis</a></code>)</li> + + <li><strong>cgi-script</strong>: Treat the file as a CGI + script. (<code class="module"><a href="./mod/mod_cgi.html">mod_cgi</a></code>)</li> + + <li><strong>imap-file</strong>: Parse as an imagemap rule + file. (<code class="module"><a href="./mod/mod_imap.html">mod_imap</a></code>)</li> + + <li><strong>server-info</strong>: Get the server's + configuration information. (<code class="module"><a href="./mod/mod_info.html">mod_info</a></code>)</li> + + <li><strong>server-status</strong>: Get the server's status + report. (<code class="module"><a href="./mod/mod_status.html">mod_status</a></code>)</li> + + <li><strong>type-map</strong>: Parse as a type map file for + content negotiation. (<code class="module"><a href="./mod/mod_negotiation.html">mod_negotiation</a></code>)</li> + </ul> + </div><div class="top"><a href="#page-header"><img alt="top" src="./images/up.gif" /></a></div> +<div class="section"> +<h2><a name="examples" id="examples">Examples</a></h2> + + + <h3><a name="example1" id="example1">Modifying static content using a CGI script</a></h3> + + + <p>The following directives will cause requests for files with + the <code>html</code> extension to trigger the launch of the + <code>footer.pl</code> CGI script.</p> + + <div class="example"><p><code> + Action add-footer /cgi-bin/footer.pl<br /> + AddHandler add-footer .html + </code></p></div> + + <p>Then the CGI script is responsible for sending the + originally requested document (pointed to by the + <code>PATH_TRANSLATED</code> environment variable) and making + whatever modifications or additions are desired.</p> + + + <h3><a name="example2" id="example2">Files with HTTP headers</a></h3> + + + <p>The following directives will enable the + <code>send-as-is</code> handler, which is used for files which + contain their own HTTP headers.

Handlers are implemented as they were + before, albeit using the handler name instead of a content + type. While it is not necessary, the naming convention for + handlers is to use a dash-separated word, with no slashes, so + as to not invade the media type name-space.</p> + </div></div> +<div class="bottomlang"> +<p><span>Available Languages: </span><a href="./en/handler.html" title="English"> en </a> | +<a href="./es/handler.html" hreflang="es" rel="alternate" title="Español"> es </a> | +<a href="./fr/handler.html" hreflang="fr" rel="alternate" title="Français"> fr </a> | +<a href="./ja/handler.html" hreflang="ja" rel="alternate" title="Japanese"> ja </a> | +<a href="./ko/handler.html" hreflang="ko" rel="alternate" title="Korean"> ko </a> | +<a href="./ru/handler.html" hreflang="ru" rel="alternate" title="Russian"> ru </a> | +<a href="./tr/handler.html" hreflang="tr" rel="alternate" title="Türkçe"> tr </a></p> +</div><div id="footer"> +<p class="apache">Copyright 2009 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>
