until now whenever i opened a new browser window, zope asked for user/psswd. however, today i tried it on a diff computer (w/ an older version of ie i belive..) and it did not ask for authentication if an authenticated user already has a window open. so, i closed all browser windows, but the old user was still authenticated. i have not checked but i'm sure the connectino will timeout after a while. SO i would like to now how i can provide the user w/ a 'log out' button so they can make sure that they have been logged out of the site, as the content displayed for each user is different/for their eyes only. i know the problem would be solved most likely by updating the brower, but since there will be a large amount of users, i cannot control that...
