Session Management

quick question

do I need to call session_start()
on every page? and session_register("SESSION")


to keep the variable session?
when i've tried putting session_start() on any page...when i hit the back button it gives me an expired error

Yes you do... I stopped using sessions because of people complaining about the expired errors.

Hi!
I'm not sure what is the cause of this behavior because i didn't test it.
You should check in [session] section of php.ini file to see if
variable "session.cookie_lifetime" is set to 0.
You can see there the reason of this value.
Best regards!
