The PHP session system uses cookies to track users by default. (The
browser sends the a cookie created by PHP with a phrase PHP can use to
lookup up user information). If PHP can't use cookies (i.e. you set
it), it tags the session ID along on every URL. You're not missing out
on anything. Cookies are actually prefered because they are more secure
and make URL look better.
