@ianswett > In this case, in order to ensure the GOAWAY doesn't reference an invalid Stream ID, you need to be able to query the type of a Stream ID even if the stream hasn't been created. I don't see why this is a problem - the stream ID value indicates the type even if an instance of that stream does not exist in a connection. In fact, we rely on this when GOAWAY with MAX_CLIENT_INITIATED_BIDI is sent. @kazuho > One trivial example is the value of GOAWAY.stream_id when the server closes an HTTP/3 connection that has carried no request. In such case, it is my understanding that GOAWAY.stream_id should be zero. But how does the server determine that value? Spec says: > This identifier MAY be zero if no requests were processed. I think MT's example is pretty straightforward way to account -- You are receiving this because you are subscribed to this thread.
