Irule for fire and forget https virtual server

Hi, the TCP::respond wasn't working, I've tried sideband, but whatever I do the connection to the client terminates before the request is sent to the server.

The request to the external server is https, so I have had to put another virtual server in the route as it seems sideband connections have to be non ssl. (I don't have irules LX setup).

Client req https -> virtual -> sideband http -> virtual -> https external server

It seems impossible to do an async fire and forget request!
