Checking for cookies/session_existance.. very basic.

I must be doing something very simple wrong.. I want to reject a user from my site if they aren't using cookies (for lack of a better method right now.. people who reject cookies can currently abuse the site I am working on).. I thought this code would do it: (start session) (register var) if (!session_is_registered("my var")) { exit(); } but it doesn't work.. can someone clue me into what I'm doing wrong? Thanks, Chad Day Beach Associates When I speak german... I think german in my head... but like...Do skript kiddies see a w40l3 8uncha 1's and 0's and 3's and 4's and 7's in their h34d'5 w43n t43y R +a1k1n6 ? -- SirStanley
