Since http is stateless there is really no good universal way to handle session management. You have to pick the lesser of the evils depending on your application. Besides cookies:

• You could use fat links containing a session id. This would require dynamically generated pages.
• If you can set up your page using form buttons for the links you can put a session id in a hidden field
• You could track sessions by IP address, but this creates problems when your potential visitors are sharing an ip address through a proxy server
• If using basic user authentication, you can associate sessions with $ENV{REMOTE_USER}.

There may be other tricks out there too. Look on CPAN for CGI:Session. The readme file has a decent discussion on this. Though I can't personally vouch for the module - I downloaded but never tried it out - it may be just what you need.
