Add functionality to existing PHP Authentication Script

I need an improvement to this script. Right now, it provides secure access to a specific page, if you navigate to another page with the same protection settings it asks again for the login. What it needs to do is maintain the login info during the entire session so that if user test2 logs into page test2 goes to page test2a or page test2b it will not ask for login unless the session has expired. I expect this will be done by adding a function that keeps track of the current session across multiple pages. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
