Ok, here's what I need to do - maybe someone can at least point me in the right direction and tell me if it's possible:
When a user enters a valid username/password from my database, a new session should be started. That session should remain active via everypage the access for as long as they stay within this site. Once they leave that domain, or simply close the browser, the session should be terminated and never used again. If someone were to try to access the site at a later time using that sessionID, it should force them back to the home page to re-login. Is this possible? If so, how does that work? I've read and read several of the session articles and the documentation at php.net and I simply don't understand how to implement a session and how it all works.
Thanks yet again,
Seth
