There are lots of ways of finding out what happens when a request comes in. Read the debugging section of the mod_perl Guide: http://perl.apache.org/guide. I favour tailing the error_log and printing truckloads of debug info in there as a matter of routine. (Amazing what you find, sometimes. :) Browsers like Netscape can fire off lots of parallel requests. You might not expect them to do that. Even if everything works like you expect, if it runs on a Webserver how are you going to prevent people double-clicking, or lots of people all clicking at once? You'd better fix your code so it can cope. 73, Ged.
