: session problem

I want to use sessions to check wether a user is logged in or not. Therefore,I use session_start and session_register. When I registere the values on the same page, they all seem to work. But when I ask the value of a registered session variable on another page, it is empty?!?! Does anyone know how this comes? i am using session_start() at every page.. i believe it must be in my php.ini setting because on my hosting provider it does work all correctly.. can anyone helpme? _________________________________________________________________ Play online games with your friends with MSN Messenger http://messenger.msn.nl/
