Hi,

Reading section 4.2.7 of draft-ietf-quic-http-09, it says:

   The GOAWAY frame does not define any flags, and the payload is a QUIC
   Stream ID for a client-initiated, bidirectional stream encoded as a
   variable-length integer.

Steam 0 is the first client-initiated, bidirectional stream. However, it is reserved for the transport's cryptographic operations.

So how would you handle a client that opens a connection but delays sending requests (for some reason)?

Regards
Lucas

P.S

While I'm here, section 4.2.7 later says:


   An endpoint MAY send multiple GOAWAY frames if circumstances change.

   For instance, an endpoint that sends GOAWAY without an error code

   during graceful shutdown could subsequently encounter an error

   condition.


Is this reference to "an error code" supposed to be in relation to CONNECTION_CLOSE or APPLICATION_CLOSE, or is it a hangover from some older version of GOAWAY?
