Would it be possible to add a simple loop detection for "moved permanently" response codes? We've been hit a couple of times with loops from URLs like http://wwwcache.localtechwire.com/favicon.png. I know the fix should really go into the browser, but IE is broken and Microsoft won't fix it. See http://connect.microsoft.com/IE/feedback/ViewFeedback.aspx?FeedbackID=357905 I was thinking a simple string compare of the requested URL and the contents of the 'Location:' field. If the two are the same it's a loop. Mike Mitchell SAS Institute Inc. Mike.Mitchell@xxxxxxx (919) 531-6793
