Document: draft-ietf-httpbis-bcp56bis-13 Reviewer: David Schinazi Review Date: 2021-08-12 IETF LC End Date: 2021-07-23 IESG Telechat date: Not scheduled for a telechat Summary: Well-written and easy to read document. Major issues: None Minor issues: * s4.5 seems to prohibit defining new non-generic HTTP methods. How do we reconcile that with the work happening in MASQUE? I know that CONNECT is its own special-case, but should we have a carveout here? (Though MASQUE might end up using extended CONNECT which side steps the issue). Or is it the case that MASQUE is modifying HTTP itself instead of building an application over HTTP? Nits/editorial comments: * s3.2 uses the term "link" without explaining what it is. Perhaps a reference to RFC 8288 if that's what is meant here? * s4.11 mentions HTTP/3 without referencing its specification
