Hello, On the archive i got the way to logout from the basic authentication. i have DTML method called "logout" with only : <dtml-raise Unauthorized> <H1>Logout requested. OK</H1> </dtml-raise> Calling the logout method calls the authenticated window. And i can give a new id/pass. So login as a new user works fine. But if i only want to became Anonymous again, when i click on the CANCEL button, i have the <H1>Logout requested. OK</H1> message at the end of the regular traceback with the Unauthorized error.. I tried to modify my standard_error_message to catch it but with no luck (i still catch other errors within my standard_error_message for generate a clean page). Anyone succeeded in generating a clean "you've been logout" page with this method ? Didier.
