|
<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>
