Blue Coat Proxy Authentication Pop-ups
Hello world, since a while we have a problem with our authentication against a Blue Coat ProxySG (v6.2.15.1). We are using NTLM authentication. With IE, no problems occur. With Firefox, while calling certain homepages, we are getting lots of authentication pop-ups (screenshot) but the webpage is not loaded correctly though. We tested Firefox version 20, 30, and 35.
We have followed many helping guides we found in the Internet, e.g., toggling the websocket (http://bluecoat.force.com/knowledgebase/articles/Solution/FirefoxpopstwiceUserAuthenticationlikemoz-proxyxxxxxxxxxxxwhenbrowsingtowebsitesusingWebSocketprotocol) or configureing the trusted-uris (https://bto.bluecoat.com/webguides/proxysg/security_first_steps/Content/Solutions/Authentication/IWA/IWA_browser_config_ta.htm) but nothing yet worked.
Our test homepage is always http://www.mediamarkt.de because it could be 100 % reprocuded that when calling this page the pop-ups appeared while the page was not loaded successfully.
Maybe someone has an idea? Thanks for any help!
Ludwig

Hi Fred, thanks for your help. Unfortunately it doesn't solve our problem. I have tested all of your hints but the same authentication pop-up is still coming.
I am still wondering why this happens only on *some* pages. Maybe it has something to do with a certain complex homepage? Since "small" pages such as www.heise.de have no problems, but only "huges" pages such as www.mediamarkt.de make problems.
Thanks again, Ludwig
Well, for one thing, that clip is for a pay site. Is that a site you want to access?
This is only a test site because our problem can be reproduced there. (It is a common german site, though). However, we have the problem on many other sites!

Something on your computer, with or without Firefox, is trying to make contact with that site. Open your file browser, and search from the root directory C:\ for the site. Use only a small part of the name.
Also, open the registry editor, and search there also. RegEdit. DO NOT change anything unless you know what you are doing. If you find it here, take a screen shot of the whole window.
