We are seeking for this review so that issues/advice are taken into account early in the process.

We are particularly interested in comments about the handling of H3, especially with regards to the guidelines in RFC9250 about HTTP versioning.

The current version focuses on H2 with the intent to cover at least common H2/H3 functionalities.

Of course, comments related to other considerations in the draft are more than welcome.

Thank you

My apologies for a late early review(!?!).

I might be confused about this, but I see that this specification uses these
HTTP2 settings

0x02     SETTINGS_ENABLE_PUSH (a BCP14 “MUST”), and

RFC 9114 reserves these in the parallel HTTP/3 registry
(, and says this
about these reserved values in Defined SETTINGS Parameters

Setting identifiers that were defined in [HTTP/2] where there is no
corresponding HTTP/3 setting have also been reserved (Section 11.2.2). These
reserved settings MUST NOT be sent, and their receipt MUST be treated as a
connection error of type H3_SETTINGS_ERROR.

Is that going to be a problem?

I’m also wondering if you need in-order delivery of results across multiple
QUIC streams. If you do, could you please let me know?

I hope this is helpful.

p.s. I should also let someone know that the HTML version of this draft says
it's -00 in the heading, but the date matches the date for -01, so I THINK I
was looking at the right version, but I've never seen that before.
