SSL Intercept and clearing certificates

Hi,

 

In case of SSL Intercept LTM is creating on the fly certificates on the client side to decrypt traffic.

 

I can see in VS stats in SSL Forward Proxy for client profile position:

 

Cached certificates: X

 

Is there a way to see list of this cached certs or clear this cached certs?

 

Is there any setting responsible for how log those certs are cached? I assume that not the ones for Cache Size and Cache Timeout (in clientssl profile as well)?

 

Piotr
