I'm working on a web app using PHP on Apache. $_SESSION variables are used quite a bit for the information that must persist across pages.
We need each user to be able to open multiple concurrent sessions, either as new tabs or new windows, depending on their choice of browser. Right now when a user opens an addition tab or window and goes to the site the existing session is adopted. How can I prevent this so that the user must (or may) log in and start a new session, without it interfering with any existing session(s) they already have open?
Our temporary workaround is to use multiple browsers (IE and FF) but that's obviously not a very desirable way of doing things.
