What is the easiest way to achieve this? Reading Nick Kew's
excellent Apache
Modules Book I've found the function ap_internal_redirect(), but
does this
function also work from an input filter? Currently I doubt it
because the first
line of the HTTP request for the backend web server is built very
early in
ap_proxy_http_request(), apparently before running the input
filters...
Do you have any better suggestion?
What else should I keep in mind in this situation?
It depends, do you want the subrequest to replace the main request? Or
do you want the subrequest to happen, and then for the main request to
continue as it was before?
