Web site SSL (TLS) usage.

Hello guys,

Anyone know if there is a programmatic way of identifying if particular website is requiring SSLv3 or TLS1.2 ? For example if you have an older version of OS (like old Win Srv 2003) and you want to open any SSLv3 requiring site with IE - you will fail to load it since win 2003 does not support SSLv3 or TLS 1.2.
So - anyone know how to grammatically (for example from C#) identify if the site required SSL ? If I raise a request to the site from C# I just get no response if my machine does not support SSL v3.

Thanks!
