A couple of small changes to prevent the "No Data" errors that
netscape gives when logged in using another browser. Most of the problems stems from the desire to allow users to refer to the main page in http mode even when logged in. I want to draw the menu as if logged in, but have the actual pages demand https mode. I'm also trying to catch the case where users have turned off cookies. I think Mac's idea is the way to go, but I don't want to mess with it right now. These changes will avoid the worst problem.
