Hi, We have a server and have noticed that one of our internal websites will no longer open on this server in Firefox 4.0.3. It will open with no problems at all in Chrome. It will also not open in IE9. I have no idea why this is happening. The error message in Firefox is ""Bad Request - Invalid Hostname \\\\ HTTP Error 400. The request hostname is invalid.""

I have cleared cache, cookies and also deleted and re-installed Firefox on this server but site still doesn't work. Other internal/external sites open in Firefox with no problem. And have done some research online without success.

Forgot to mention that this website that will not open in Firefox on the server opens with no problem in Firefox on our PCs.
