<h3>Summary</h3>
|
||
|
||
<p>This module <em>requires</em> the service of <code class="module"><a href="../mod/mod_proxy.html">mod_proxy</a></code>. It provides support for the passing the socket of the
|
||
client to another process.</p>
|
||
|
||
<p><code>mod_proxy_fdpass</code> uses the ability of AF_UNIX domain
|
||
sockets to <a href="http://www.freebsd.org/cgi/man.cgi?query=recv">pass an
|
||
open file descriptor</a> to allow another process to finish handling a request.
|
||
</p>
|
||
|
||
<p>The module has a <code>proxy_fdpass_flusher</code> provider interface,
|
||
which allows another module to optionally send the response headers, or even
|
||
the start of the response body. The default flush provider disables keep-alive,
|
||
and sends the response headers, letting the external process just send a
|
||
response body.</p>
|
||
|
||
<p>At this time the only data passed to the external process is the client
|
||
socket. To receive a client socket, call recvfrom with an allocated
|
||
<a href="http://www.kernel.org/doc/man-pages/online/pages/man3/cmsg.3.html"><code>struct cmsghdr</code></a>. Future versions of this module may include
|
||
more data after the client socket, but this is not implemented at this time.
