Technical Summary This document creates an HTTP/2 [RFC7540] extension for finer grained control of connection management than is provided by the base HTTP/2 specification. In this context that specifically means the set of origin names that may be served on one connection. The document provides for changing that set to be both smaller or larger than the default. Working Group Summary Two key aspects of the draft, the ability to remove origin names from the default set and the syntax to manage the set, underwent several iterations based on the working group's feedback and arrived at a strong consensus. The aspects of this document dealing with the relationship of HTTPS connection management and DNS were the most controversial and required the most change to reach consensus. This mechanism addresses experience with RFC 7540 which shows the existing DNS based mechanism is administratively onerous and error prone. The change also has benefits for performance and confidentiality. On the other hand, the change increases the importance of proper certificate security because key compromise can now be exploited without being an on-path attacker. The final position of the draft is that an Origin extension relaxes the requirements for name resolution (but never certificate verification) if a client concludes the new risks are mitigated by alternative signals that boost confidence in the certificate. The Security Considerations deals with the topic at some length. This position reached rough consensus. Document Quality Participation in the document's review and discussion was unusually broad based with members of the community from many roles taking part (browsers, servers, CDNs, security engineers, etc..). There is broad agreement that the functionality provides benefits to HTTP latency, efficiency, and administrative flexibility. There are statements of intent to implement from browser, servers, and CDNs. There is an existing browser implementation.
