51 <p>Under normal circumstances, request handlers such as the
52 default handler for static files will discard the request body
53 when it is not needed by the request handler. As a result,
54 filters such as mod_include are limited to making <code>GET</code> requests
55 only when including other URLs as subrequests, even if the
56 original request was a <code>POST</code> request, as the discarded
57 request body is no longer available once filter processing is
60 <p>When this directive has a value greater than zero, request
61 handlers that would otherwise discard request bodies will
62 instead set the request body aside for use by filters up to
63 the maximum size specified. In the case of the mod_include
64 filter, an attempt to <code>POST</code> a request to the static
65 shtml file will cause any subrequests to be <code>POST</code>
66 requests, instead of <code>GET</code> requests as before.</p>
68 <p>This feature makes it possible to break up complex web pages and
69 web applications into small individual components, and combine
70 the components and the surrounding web page structure together
71 using <code class="module"><a href="../mod/mod_include.html">mod_include</a></code>. The components can take the
72 form of CGI programs, scripted languages, or URLs reverse proxied
73 into the URL space from another server using
74 <code class="module"><a href="../mod/mod_proxy.html">mod_proxy</a></code>.</p>
76 <p><strong>Note:</strong> Each request set aside has to be set
77 aside in temporary RAM until the request is complete. As a result,
78 care should be taken to ensure sufficient RAM is available on the
79 server to support the intended load. Use of this directive
80 should be limited to where needed on targeted parts of your
81 URL space, and with the lowest possible value that is still big
82 enough to hold a request body.</p>
84 <p>If the request size sent by the client exceeds the maximum
85 size allocated by this directive, the server will return
86 <code>413 Request Entity Too Large</code>.</p>
