sanity check, are you doing anything w/ $_SESSION['ok'] or the session at all on the webbytedd.com homepage? i dont think $_SESSION['ok'] is being set to 0, nor is the session being destroyed (unless youre doing something w/ it when building your webbytedd.com homepage). > Please follow, if a user goes to: > > http://webbytedd.com/b1/simple-session/ > > enters 'guest' travels the site, leaves, and returns -- they are presented > with another logon page, just like the first time. if i leave and return, im not redirected. i just get the page i ask for. for example, if i authenticate by entering 'guest' at the first page. then close the tab with your site, then open a new window (or tab) and paste in the url to one of the protected pages, like http://www.webbytedd.com/b1/simple-session/index2.php i go right to it, no redirect. because i havent hit any code to destroy the session, or change the value of $_SESSION['ok'] to 0.
