Sorry for disagreeing, but of course it is a proxy specific issue; As
far as I know, no other module connects to another server (ignoring
mod_rewrite which uses mod_proxy for this purpose).
And as the original sender hinted by the "Subject" header, it is easy
to implement: just "bind()" the required IP into the socket before
calling "apr_connect()" (it may require a minor fix in APR, I'm not
sure).
Port number should be left 0, to let the kernel choose its own
ephemeral port.
I believe that we should give more attention to this question. In my
first look, it is easy to add directives ("ProxyIP"/"ProxyHost"?) and
code to implement it ("bind()"), and it looks useful for some needs.
Even without the additional directive, when the original request
reached to a specific vhost, it would make sense to bind the outgoing
socket to the IP of that vhost (as the original sender wished).
