Meta files are HTTP 38 headers that can be output in addition to the normal range of 39 headers for each file accessed. They appear rather like the 40 Apache .asis files, and are able to provide a crude way of 41 influencing the Expires: header, as well as providing other 42 curiosities. There are many ways to manage meta information, 43 this one was chosen because there is already a large number of 44 CERN users who can exploit this module.</p> 45 46 <p>More information on the <a href="http://www.w3.org/pub/WWW/Daemon/User/Config/General.html#MetaDir">CERN metafile semantics</a> is available.</p> 47</div> 48<div id="quickview"><h3 class="directives">Directives</h3> 49<ul id="toc"> 50<li><img alt="" src="/images/down.gif" /> <a href="#metadir">MetaDir</a></li> 51<li><img alt="" src="/images/down.gif" /> <a href="#metafiles">MetaFiles</a></li> 52<li><img alt="" src="/images/down.gif" /> <a href="#metasuffix">MetaSuffix</a></li> 53</ul> 54<h3>See also</h3> 55<ul class="seealso"> 56<li><code class="module"><a href="/mod/mod_headers.html">mod_headers</a></code></li> 57<li><code class="module"><a href="/mod/mod_asis.html">mod_asis</a></code></li> 58</ul><ul class="seealso"><li><a href="#comments_section">Comments</a></li></ul></div> 59 60<div class="top"><a href="#page-header"><img alt="top" src="/images/up.gif" /></a></div> 61<div class="directive-section"><h2><a name="MetaDir" id="MetaDir">MetaDir</a> <a name="metadir" id="metadir">Directive</a></h2> 62<table class="directive"> 63<tr><th><a href="directive-dict.html#Description">Description:</a></th><td>Name of the directory to find CERN-style meta information 64files</td></tr> 65<tr><th><a href="directive-dict.html#Syntax">Syntax:</a></th><td><code>MetaDir <var>directory</var></code></td></tr> 66<tr><th><a href="directive-dict.html#Default">Default:</a></th><td><code>MetaDir .web</code></td></tr> 67<tr><th><a href="directive-dict.html#Context">Context:</a></th><td>server config, virtual host, directory, .htaccess</td></tr> 68<tr><th><a href="directive-dict.html#Override">Override:</a></th><td>Indexes</td></tr> 69<tr><th><a href="directive-dict.html#Status">Status:</a></th><td>Extension</td></tr> 70<tr><th><a href="directive-dict.html#Module">Module:</a></th><td>mod_cern_meta</td></tr> 71</table> 72 <p>Specifies the name of the directory in which Apache can find 73 meta information files.
