Session understanding

Hello, Morning .. at least it is where I am :) I have a small issue with sessions, at the moment I am using sessions on our web site and storing the session information in a db_table. It is working great. Right now I am only storing the users ID, name and role in the session data, but I would like to store other information as well. The problem is ... that if that person opens another browser window and connects to the site another session is not created. So if I try and store a variable that would be unique to each window it would get over written. Is this a configuration problem ? Thanks. -- Michael Gale Network Administrator Utilitran Corporation
