I would like to propose renaming REFUSED_STREAM to RETRY_STREAM.

IMO, REFUSED_STREAM doesn’t match the definition of the word “refused” because there is a time component i.e. the server decided, for whatever reason, to not accept the stream *right now*, but you can try again later.

refuse /rɪˈfjuːz/


past tense: refused; past participle: refused

     indicate or show that one is not willing to do something. [1]

From Section 7 [2]:

REFUSED_STREAM (0x7):  The endpoint refuses the stream prior to performing any application processing, see Section 8.1.4<> for details.

From Section 8.1.4 (emphasis added) [2]:

The REFUSED_STREAM error code can be included in a RST_STREAM frame to indicate that the stream is being closed prior to any processing having occurred. Any request that was sent on the reset stream can be safely retried.


Requests that have not been processed have not failed; clients MAY automatically retry them, even those with non-idempotent methods.

Proposed change:

RETRY_STREAM (0x7):  The endpoint closed the stream prior to performing any application processing.  Any request that was sent on the reset stream can be safely retried, see Section 8.1.4<> for details.
