Client Authentication Certificate APM

so correct me if im wrong, you want the certificate on the F5 to be shown to the client and the client certificate passes to the pool member? that isn't possible, SSL offloading means the client certificate is lost there. you can pass it in header or such, but not the actual certificate as part of the SSL information.

if you need the client certificate at the poolmember isn't tcp load balancing an option, you do miss the ssl offloading then of course.
