What does the session hash do?

I was curious what the session hash does. It's that $s= in the query. Also, what does clearing it do when it's just $s= and not the numbers/letters following it.

The sessionhash in the URL is what vBulletin uses to keep your session alive (aka keep you in a 'logged in' state). When it does not appear in the URL it means the user has selected to have it stored as a cookie instead of being put in the URL.
