You run an application that uses port 443 to connect to a remote web server in a Microsoft Forefront Threat Management Gateway 2010 environment. After you enable HTTPS inspection (HTTPSi), the application no longer functions.
This problem occurs because HTTPSi always performs a secure socket layer (SSL) handshake to the destination web server even if the web server is not running SSL.
To resolve this problem, install the service pack that is described in the following Microsoft Knowledge Base article:
2555840Note After you install Service Pack 2, you can exclude the web servers from the inspection by adding them to the HTTPSi destination exclusion list.
