Well, no thought. What I do when I'm clueless is compiling an apache
server with debug symbols (CFLAGS="-g -O0 -fno-inline"), configure it,
and start it in debug mode (apache2 -f my_conf.conf -X) in a debugger.
Then I set a breakpoint on ap_invoke_handler or on other functions in
the request processing call-stack, send a HTTP request and run the
server step-by-step. It's labour-intensive until you have set up all
your environment, but you can reuse it and it helps development and
diagnosis significantly.
