I haven't checked the cookie content, but as I said I did toss the cookies and clear the cache before retrying it. I even closed all the Firefox tabs that had any pages open from the server and did it again. On the Nth restart of the server after this, the problem cleared, so debugging will have to wait until it resurfaces. Since this was only a development/test/experimental instance, it wasn't crucial, and wouldn't have been until I started tearing my hair out over having to use IE. Thanks again. By the way, might there be anything identifiable in the cookie - fingerprints, or a smoking gun, or a deathbed confession - in case I see it again? Looks like that bit of javascript would make a handy bookmarklet... brain[sic] -----Original Message----- From: Ludovic Dubost [mailto:ludovic@xwiki.com] Sent: Tuesday, April 11, 2006 3:32 PM To: xwiki-users(a)objectweb.org Subject: Re: [xwiki-users] Help with login confusion What do you have in javascript:alert(document.cookie) You might want to clean up your cookies and start over Ludovic THOMAS, BRIAN M (SBCSI) a écrit : -- Ludovic Dubost XPertNet: http://www.xpertnet.fr/ Blog: http://www.ludovic.org/blog/ XWiki: http://www.xwiki.com Skype: ldubost AIM: nvludo Yahoo: ludovic
