Just out of interest...

Say you've got 5 users logged in to a website. The server is holding info like username, password, email address etc for each user in session variables. (That's how the page knows if the person really is logged in or not)

Is there a way of viewing all the server variables for all the users? And seeing how long they session variables have left (till they expire etc). A kinda "Session Browser"...you know?
