I think this is what's happening: IE8 doesn't support multiple  
background images per CSS, thus trying to load everything after  
background-image:url(. This is loading a non-existant URL which is  
catched by Horde's rampage.php which requires authentication. Since  
you don't use session cookies, this is an unauthenticated request.
