HTTP::respond Command in the CLIENTSSL_HANDSHAKE Event

Can't do links in a comment so just to continue, on the plus side, all this work has enabled me to come up with this HTTPS/SSL event order diagram which I'm sure I and others will find very useful in future. Still a few update due but it's accurate: https://devcentral.f5.com/questions/irule-event-order-https-ssl-client-server-side (as far as I know).
