Re: PHP Sessions

Your assumption is correct. When you create a session there are 2 ways it gets tracked. Via URLs or via the session Cookie. By default, it is stored in Cookies when it can. So when you do session_name('TEST'), a cookie named TEST will be created and it would have the value of the session id.
