Force connection close after protocol upgrade #3126

RFC 6455 states that closing a WebSocket must close the underlying TCP connection:
-- https://datatracker.ietf.org/doc/html/rfc6455#section-5.5.1 I couldn't find any language about this in the HTTP/2 protocol, but it seems safer to me to assume that the socket is in an unknown state and any connection persistence is managed at the level of the new protocol. |
A new protocol, such as WebSockets or HTTP/2, may manage the framing of multiple messages or requests of that protocol over a single connection, but the connection should close once the WSGI callable returns. - Close connections after completion of any upgraded response. - Close connections after a response with status code less than 200. Any such response should be only for a protocol upgrade since applications never see any `Expect` header. - Ensure that the `status_code` member always exists on instances of the `Response` class (close #1210).

There was a problem hiding this comment.
why changing the logic there ? Also this doesn't take care anymore about status code < 100. Can you elaborate? (As a side note I'm not a fan of these one line boolean combination, decoupling in multiple if helps to trace the code .
