Hi Ker, It'll be the web server which is handling the requests obviously - probably Apache. If your running Perl CGI without mod perl installed in Apache then each request for the CGI will, I believe, cause another external process to be created invoking the system Perl compiler, the compiled results are then executed and the resutls returned the webserver for returning to the client - the compiled script is then effectively 'lost' - the next request to the CGI starts the cycle again. mod-perl effectively stored the compiled perl script to minimise the recompilation process and uses a Perl compiler embedded into Apache itself for maximum speed. mod-perl does have its own gotchas when dealing with multiple requests which are well documented.
CGI Carp will give you plenty of stuff to look at in the web browser rather than the dreaded 500 error. And I bet there is module for Perl to write to the Apache log - search on search.cpan.org and I'm sure you'll find one. regards Joel -----Original Message----- From: Kerr Wall [mailto:[EMAIL PROTECTED]] Sent: 16 July 2002 17:54 To: [EMAIL PROTECTED] Subject: Couple of newbie questions Hi All, I am currently switching to Perl/CGI from the Java servlet world. I'm wishing I would have made this switch a long time ago and I have a couple of questions: How does perl handle multiple requests. For example, if 10 users are logged into your system and they are all trying to use the same script, how does perl deal with this situation? What is the best way to test and debug? I am use to printing to the console with Java and I'm not sure how I do this with perl. Does apache have a log file that I can write to and how to I keep track of when I want to print the response or print to stdout/log file?
