If you're doing everything correctly, why is there a problem? Why can't you figure it out and fix it?

See CGI::Session "cache" issue/Re^3: CGI::Session "cache" issue where another person thinks CGI::Session isn't doing something correctly ... but at least he posted more code

You're not the first to say there is a problem with CGI::Session , see Re: ie with cgi::session not showing same session id which it was set and firefox doesn't show at all, but you haven't shown any code that proves/demonstrates/shows a problem with CGI::Session -- you have not shown enough code -- the problem is with your code

If you want to figure it out, check my links, try the debugging steps ... or post more code
