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