Thanks!
This is definitely not what I asked for :-)

I want to do OCSP.
But if the HTTPS server doesn't staple a status response - then my only opportunity is during verify callback.
Even if it did - it would only be for the leaf certificate, and I am after good status throughout the chain.
However - I don't know how to recall the OCSP resolver of the underlying IO::Socket::SSL instance from within the callback.
That's my question

I did try to connect/disconnect the IP and port from the URL, and do the OCSP there, and only proceed to the actual request if this "tls-ocsp-ping" was successful.
However, this approach can have a performance impact, as the LWP::UserAgent with keepalive will not re-do a TLS handshake for every request (to same server).
