Websocket config in F5 11.4.1

From what I understand is you need to disable the HTTP profile from processing when the "websocket" has established it's connection, as the profile doesn't understand websockets.

You can code an iRule, with somthing similar to this:

when HTTP_REQUEST {
  if { [string tolower [HTTP::header Upgrade]] contains "websocket" }{
      HTTP::disable
  }
}
