We havenít discussed much yet, but there are two (not necessarily exclusive) proposals:

- You try; if the other end doesnít support WS, it refuses with an error code.

- You discover what schemes the server supports using a SETTINGS.

This assumes you already have an HTTP/2 connection open to the server; if you donít, you have to figure out what to do, but I *think* thatís a WS/1 problem, not ours.
