With ASP you can set a session variable on site A. Site A can the link to site B which links to C and so on. Within the time limit if you link back to site A your session information is still there.
My problem is PHP requires the session_id to be passed in the URL for each page or stored in a cookie (which defeats the point of a session cookie). Is there no other way?
I'm currently using a cookie which runs into problems with users having then disabled. (I've found alot more have session cookies enabled) I've tried using IP addresses but an office behind a firewall all have 1 IP address so that works worst then a cookie.
Any suggestions?
