GOAWAY sent mid-connection

Stop opening requests, finish those in flight, and retry idempotent ones elsewhere. The GOAWAY is written once the client's request is running and names the stream after it, so §5.2 puts that request inside the range the server promises to process: finishing it is the behaviour under test. Sent before the request instead, the correct answer would be to close and reconnect, and the test would be measuring a race rather than recovery.

What the clause requires

Stop opening requests, finish those in flight, and retry idempotent ones elsewhere. The GOAWAY is written once the client's request is running and names the stream after it, so §5.2 puts that request inside the range the server promises to process: finishing it is the behaviour under test. Sent before the request instead, the correct answer would be to close and reconnect, and the test would be measuring a race rather than recovery.
