Hello,

Need a clarification regarding section 5. It says:

   Implementations using this extended CONNECT to bootstrap WebSockets
   do not do the processing of the [RFC6455] Sec-WebSocket-Key and Sec-
   WebSocket-Accept headers as that functionality has been superseded by
   the :protocol pseudo-header.

does that mean that a transparent proxy (say, a CDN, as opposed to a
traditional HTTP CONNECT proxy) that proxies WS connections and speaks HTTP/2
with the client but HTTP/1 with the origin server, is expected to generate
-Key and validate -Accept itself? Might be worth mentioning this in section 7
as well.

Cheers
