SYMPTOMS

In Microsoft Internet Security and Acceleration (ISA) Server 2006, you publish a Web server and enable redirection from HTTP to HTTPS. When a client tries to connect to this Web server, port 0 is appended to the URL. Therefore, if a user uses a browser other than Internet Explorer, the user will not be redirected to the correct Web server.

For example, the URL may resemble the following:
https://www.contoso.com:0/index.htm
This problem occurs if the following conditions are true:
  • A Web listener is configured to listen for connections on port 80 (HTTP) and port 443 (HTTPS).
  • The Web listener is configured to redirect from HTTP to Secure Sockets Layer (SSL).
  • The network where the Web listener operates also has automatic discovery enabled on port 80.
Note This problem does not occur when you use Internet Explorer.

To resolve this problem, apply the hotfix that is mentioned in the following Microsoft Knowledge Base article:
