Consider the following scenario:
- You are using a computer that is running Microsoft Windows XP with Service Pack 2 (SP2).
- You are running Microsoft Internet Explorer 6 on this computer.
- Internet Explorer 6 is configured to use a proxy server that is running Microsoft Internet Security and Acceleration (ISA) Server with SP2. ISA Server is running Symantec Web Security 18.104.22.168.
- The proxy server adds a “Content-length: 0” header in response to a CONNECT request from Internet Explorer 6.
In this scenario, Internet Explorer 6 crashes when you try to access an HTTPS URL through the proxy server.
This problem occurs because of a bug in the Wininet.dll file.
