MINOR: mux-h1: Force close mode for proxy responses with an unfinished request
When a response generated by HAProxy is handled by the mux H1, if the
corresponding request has not fully been received, the close mode is
forced. Thus, the client is notified the connection will certainly be closed
abruptly, without waiting the end of the request.
