I don't think this is correct. If the client encountered this error code, it would just fail the WebSocket setup attempt. In general, I don't think we should be asking clients to retry requests across different HTTP versions. If you publish wss:// URIs for your domain, you need to support WebSocket on all the domain's HTTP versions.

This draft says

Suppose the server supports extended CONNECT but= not bootstrapping WebSockets over that HTTP connection. In this case, the = client sending a WebSocket handshake request will result in a response of 5= 01 (Not Implemented) status code (Section 15.6.2 of [HTTP]), and the client= would need to fall back to trying the WebSocket handshake over HTTP/1.

I don't think this is correct.=C2=A0 If th= e client encountered this error code, it would just fail the WebSocket setu= p attempt.

In general, I don't think we should= be asking clients to retry requests across different HTTP versions.=C2=A0 = If you publish wss:// URIs for your domain, you need to support WebSocket o= n all the domain's HTTP versions.

Hello,

I have submitted an internet-d= raft proposing a=C2=A0SETTINGS_ENABLE_WEBSOCKETS settings=C2=A0parameter.
With WebSockets not being the only p= rotocol that uses extended CONNECT (h= ttps://github.com/ietf-wg-webtrans/draft-ietf-webtrans-http3/issues/68#issu= ecomment-1310323592),
Before starting the WebSocket handshake, it will be nice to know if the = server supports bootstrapping WebSockets over HTTP/2 or HTTP/3.

I would love to know your thoughts
