Ok, now I've finally understood Apache::Session I have nice little app. Inevitably I'm going to have to make it work with IIS on NT. Possibly Netscape Enterprise on Solaris too. I'm pretty sure everything else is portable (no Linux specific commands, DBI for database access etc.) but what do I do about session management? Theres a bunch of stuff on CPAN but which is the best, most robust etc? A solution has to work with HTML::Mason too. Enlighten me oh sages!
