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.
