Identify TLS version of client apps

[#1]

Hello,

I'm trying to find out if there's a way to determine the version of TLS protocol used by client developers, in other words I have a list of applications and would like to filter by TLS version used - is that possible?

Thanks

It's oh-so-close to being possible.

Apigee Engineering has built a feature to expose that information to the API Proxy in the form of "context variables." You'll be able to refer to tls.protocl and tls.cipher to examine the protocol (eg TLSV1.2) and the cipher used on the TLS session.

The bad news: This feature is documented, but... not yet released!

We expect to release this capability to the public cloud by the end of August.
