Consider the following scenario:
- You have a computer that is running a non-English version of a Windows operating system.
- You enable the HTTPS Inspection feature in Microsoft Forefront Threat Management Gateway (TMG) Server 2010 that is installed on the computer.
- You access certain Secure Sockets Layer (SSL) websites that use Subject Alternative Name certificates.
HTTP/1.1 502 - Error 11 Bad format.
- This issue does not occur if you disable the HTTPS Inspection feature in Forefront TMG Server 2010.
- This issue does not occur if the computer runs an English version of the Windows operating system.
This issue occurs because Forefront TMG Server 2010 has some hard-coded checks on non-localized strings for the SAN extension checks.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
