If the service switches to websocket using an HTTP Upgrade mechanism,
then you need at least https://github.com/squid-cache/squid/pull/481

If the service uses websocket without HTTP Upgrade negotiation, then you
need on_unsupported_protocol (with some way of detecting that service
traffic if you do not want to tunnel everything that is not HTTP(S)).
