Re: check if user session exists

Yeah, my solution so far has been to check the last modified time of the session file and then go from there. If the modified time is > then time permitted, then that file is removed and the user's session is rendered null and void. What I am doing is allowing a variable X number of user's to simultaneously log-in under the same user/pass combo (account), and the problem I face is, if none of the user's logs-out, then how will I determine when to pop an inactive account off the stack.
