I upgraded from 2.6 stable 4 to 2.6stable14 If internet explorer is configured to use the proxy and I browse to a server that pops up a username/password/domain (Windows Integrated Auth, IIS) login box, it no longer pops up , rather states: You are not authorized to view this page You do not have permission to view this directory or page using the credentials that you supplied because your Web browser is sending a WWW-Authenticate header field that the Web server is not configured to accept. However, if I do it using HTTPS, it works fine. Why is normal HTTP no longer working? - Nick
