What happened when you tried it? If you want to do some background processing without tying up the client, you'll probably want your webserver to think that you're all finished. One way to do that is to fork a child process and let the parent quit. If the child then closes the output filehandles STDOUT and STDERR, the webserver should conclude that the CGI program has finished, even though the child process is still running. Instead of simply closing the output filehandles, you could reopen them, with the output going to a file (or even /dev/null). In Perl, it's generally better to reopen the standard filehandles like that rather than closing them, so that new filehandles will be properly numbered internally. The important thing is that the webserver sees that nobody is writing to it any longer, since the filehandles are closed, so it can reply to the remote user.
