Irule request to redirect Standard HTTPS traffic to Non Standard HTTPS port.

Redirection is generally an HTTP term, which would also imply that the F5 could see the decrypted layer 7 traffic and issue an HTTP redirect. In lieu of that, it's not generally possible to issue a redirect to a client if the F5 is not offloading the SSL. ProxySSL, the SSL man-in-the-middle feature wouldn't work here because there'd be no port 443 server endpoint for the client to establish an SSL session with. You may necessarily have to simply forward the traffic and do port translation inbound. This is where the pool defines your port 9804 resources, and you ensure that port translation is enabled in the virtual server config. Client side port 443 traffic will be translated to port 9804 to the server(s).
