I have a site and one section needs to be tracked with sessions, do I need to use start_session() on every page of the site or just the section that I need to use sessions. I want to keep track of session variables and it is possible that they may navigate in and out of the section that needs sessions. So bottom line, say I have a section called members, I need to track some session info in there, and say they go to the public section of site and then go back into the members section, do I need to call satrt_session on every page?
