To proxy a WebSocket handshake, Squid has to, at a minimum, send an Upgrade header to the origin server, forward the HTTP 101 response from the origin server to the client, and then become a TCP tunnel. The last part is impossible to accomplish in v4 with configuration options alone: There is simply no "become a tunnel" directive that is checked after forwarding a 1xx control message.
