You need to 1. make sure that C::S is using the session ID to pull the previous session for a given user, and 2. make sure that the session ID is getting output to the user.
You can do 1. in two ways:
- Pass your CGI instance to C::S in the constructor. It'll do its best to look for a cookie or param with the proper name.
- You can pull the cookie or param from CGI with the session ID and pass that in.
As far as 2., your best bet is to always, no matter what, print your header as including a cookie containing the CGISESSID (or whatever you've decided to name it).
Of course, this will bomb miserably for users sans cookies. Be aware of this and consider testing for cookie usage and/or appending the ID to URLs and form variables (a PITA IMO).
