We are using proxy authentication via LDAP. This works fine for most browsers. But we have a problem using IE6SP1: After authenticating with a valid account, ie6 shows an error page "server or dns not found...". After pressing the refresh button, the url opens.
This behaviour can only be seen with ie6sp1. No problems with Opera, Mozilla, Netscape or older ie versions. What is going on? Any hints?
