As a result, 58 filters such as mod_include are limited to making <code>GET</code> requests 59 only when including other URLs as subrequests, even if the 60 original request was a <code>POST</code> request, as the discarded 61 request body is no longer available once filter processing is 62 taking place.</p> 63 64 <p>When this directive has a value greater than zero, request 65 handlers that would otherwise discard request bodies will 66 instead set the request body aside for use by filters up to 67 the maximum size specified. In the case of the mod_include 68 filter, an attempt to <code>POST</code> a request to the static 69 shtml file will cause any subrequests to be <code>POST</code> 70 requests, instead of <code>GET</code> requests as before.</p> 71 72 <p>This feature makes it possible to break up complex web pages and 73 web applications into small individual components, and combine 74 the components and the surrounding web page structure together 75 using <code class="module"><a href="/mod/mod_include.html">mod_include</a></code>. The components can take the 76 form of CGI programs, scripted languages, or URLs reverse proxied 77 into the URL space from another server using 78 <code class="module"><a href="/mod/mod_proxy.html">mod_proxy</a></code>.</p> 79 80 <p><strong>Note:</strong> Each request set aside has to be set 81 aside in temporary RAM until the request is complete. As a result, 82 care should be taken to ensure sufficient RAM is available on the 83 server to support the intended load. Use of this directive 84 should be limited to where needed on targeted parts of your 85 URL space, and with the lowest possible value that is still big 86 enough to hold a request body.</p> 87 88 <p>If the request size sent by the client exceeds the maximum 89 size allocated by this directive, the server will return 90 <code>413 Request Entity Too Large</code>.</p> 91 92 93<h3>See also</h3> 94<ul> 95<li><a href="mod_include.html">mod_include</a> documentation</li> 96<li><a href="mod_auth_form.html">mod_auth_form</a> documentation</li> 97</ul> 98</div> 99</div> 100<div class="bottomlang"> 101<p><span>Available Languages: </span><a href="/en/mod/mod_request.html" title="English"> en </a> | 102<a href="/fr/mod/mod_request.html" hreflang="fr" rel="alternate" title="Fran�ais"> fr </a> | 103<a href="/tr/mod/mod_request.html" hreflang="tr" rel="alternate" title="T�rk�e"> tr </a></p> 104</div><div class="top"><a href="#page-header"><img src="/images/up.gif" alt="top" /></a></div><div class="section"><h2><a id="comments_section" name="comments_section">Comments</a></h2><div class="warning"><strong>Notice:</strong><br />This is not a Q&A section.
