Fwd: New Version Notification for draft-ietf-httpbis-priority-00.txt

Hello WGs,

Following adoption of draft-kazuho-httpbis-priority-04 by HTTPbis, Kazuho
and I have published draft-ietf-httpbis-priority-00 (see forwarded email).

The major change in this draft relates to the urgency levels. Based on
feedback and discussion, we have kept 8 levels (0-7 in descending order of
priority) but have minimized the semantics. This allows a common urgency
range, without being overly prescriptive on client's ability to use the
range. Furthermore, the text describing how an intermediary might approach
merging priority signals from client and server implied a weighting toward
server signals; we have reduced the guidance and highlight that merging
decision are a local decision.

This draft version contains changes that reflect emerging WG consensus.
However, the list of open issues is available on Github [1] and we
encourage continued discussion, notably the debate on using frame vs.
headers is still unresolved.

Cheers
Lucas

Abstract:
   This document describes a scheme for prioritizing HTTP responses.
   This scheme expresses the priority of each HTTP response using
   absolute values, rather than as a relative relationship between a
   group of HTTP responses.

   This document defines the Priority header field for communicating the
   initial priority in an HTTP version-independent manner, as well as
   HTTP/2 and HTTP/3 frames for reprioritizing the responses.  These
   share a common format structure that is designed to provide future
   extensibility.




Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
