That isn't a dev@ list question at all; it would entirely depend how
you have configured your server (mod_cgi? cgid? fcgid? mod_perl?) and
the users@ list would be a better place to help you understand how you
have configured your server.

Determine which module you are running, or you can set a breakpoint
in the ap_process_request_internal() and ap_process_request() code 
to discover which handler accepts the request.
