This module requires the service of
mod_proxy. It provides support for the passing the socket of the
client to another process.
mod_proxy_fdpass uses the ability of AF_UNIX domain
sockets to pass an
open file descriptor to allow another process to finish handling a request.

proxy_fdpass_flusher provider interface,
which allows another module to optionally send the response headers, or even
the start of the response body. The default
disables keep-alive, and sends the response headers, letting the external
process just send a response body.
In order to use another provider, you have to set the

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
struct cmsghdr. Future versions of this module may include
more data after the client socket, but this is not implemented at this time.
This module provides no directives.
