I have a folder on my domain:
www.mydomain.com/folderA - here the session variables passed from script to script work absolutely fine for as many scripts as I can think of.
But then in this area of the site www.mydomain.com/folderA/folderB I can no longer access the folder A's session variables and I am using the same session handling methodology as in the programming in folder A.
This is all entirely on one same server. No use of cookies. All sessions are server side. I am not using session ID stuff. All the session functions I use are session_start, session_register, session_unregister and session_destroy.
Hope this makes it clear.
