Hi William, Your reply helped me . I launched httpd -X and used gdb <processID of httpd -X> and the debugger went into child_main function of prefork.c and it is remaining in while loop in the same function. What I would want is to see what module is getting invoked when a php script is run? What module is invoked when perl script is run ? I want to debug other core modules of apache like http_protocol.c , http_request.c , http_main.c.
What is the best way of debugging the above modules? Thanks, Kalyan On Sat, May 11, 2013 at 9:04 AM, William A.
