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