I've written a couple of pages that require a login in order to access. The pages determine if the person has logged in by checking a session. I've noticed in both IE 5 and NS 6 that if you login in and then open a new browser window using File>New Window, the new window appears to share the same session as the original. For the puposes that I am using sessions, it is not that big of a deal, but it does raise some interesting implications about session use. Is there a way (on the server) to force the newly opened window to use a new session?
