When a client performs an abbreviated handshake by reusing the session from a previously established full handshake, the SSL forward proxy does not raise the CLIENTSSL_SERVERHELLO_SEND event.
iRule commands inside of the CLIENTSSL_SERVERHELLO_SEND are only executed for full handshakes but not for abbreviated handshakes; thus any logic that's applied per SSL connection should not run inside of CLIENTSSL_SERVERHELLO_SEND event since it is not reliably raised under all types of handshakes.
This occurs when the following conditions are met: -- SSL forward proxy configured -- Session cache is enabled.
To make sure that the CLIENTSSL_SERVERHELLO_SEND event is reliably raised, disable session cache in the client SSL profile.
