IE 6 Bug with HTTPS POST

It looks like there is not much you can do about it. The best solution: to install a new fixpack and update the registry is not possible for a web application.

From Microsoft Support: "For example, when you submit your user name and password to an SSL-secured Web site by using a form on a HTTPS Web page, Microsoft Internet Explorer may not resend this information to the Web server if the initial connection is closed (or reset)."

"This problem occurs after you apply the 832894 security update (MS04-004) or the 821814 hotfix."
