Hi,
If a login form appears within the HTML page you're viewing, then you're using cookie authentication.
Sorry, if I didn't put my question right. I did not meant to ask the difference between basic and cookie authentication. What I fond out: If I log in in the (let's say) root-folder, an the view a document below root, I am authenticated, no matter if the object needs authentication or not. I understand that the autentication is being aquired. If I log in at object B (authentication required) and than view document A (no authentication) an the same level, I am NOT authenticated (not on aquisition path). But I can view third document (authentication required) on the same level without being asked for an authentication again, although it is not in the aquisition path of the first object. That's a bit confusing (for me) Regards Christoph
