The following errata report has been held for document update for RFC7540, "Hypertext Transfer Protocol Version 2 (HTTP/2)". -------------------------------------- You may review the report below and at: http://www.rfc-editor.org/errata_search.php?rfc=7540&eid=4666 -------------------------------------- Status: Held for Document Update Type: Technical Reported by: Vasiliy Faronov <vfaronov@gmail.com> Date Reported: 2016-04-13 Held by: Alexey Melnikov (IESG) Section: 9.1.2 Original Text ------------- A 421 response is cacheable by default, i.e., unless otherwise indicated by the method definition or explicit cache controls (see Section 4.2.2 of [RFC7234]). Corrected Text -------------- [paragraph removed] Notes ----- The HTTP cache key (RFC 7234 Section 2) is based on the request URI, not on properties of the connection. Therefore, if a client were to cache a 421 response, it would then use this cached 421 to satisfy further requests to the same URI, before it has a chance to connect to an authoritative server. Mark Nottingham: As discussed on list, I think the best we can do here is to note that in many cases, it'd be desireable to mark this as explicitly uncacheable. With this paragraph removed, a 421 response is not cacheable by default, per RFC 7231 Section 6.1. -------------------------------------- RFC7540 (draft-ietf-httpbis-http2-17) -------------------------------------- Title : Hypertext Transfer Protocol Version 2 (HTTP/2) Publication Date : May 2015 Author(s) : M.
