The IESG has approved the following document: - 'The No-Vary-Search HTTP Caching Extension' (draft-ietf-httpbis-no-vary-search-09.txt) as Proposed Standard This document is the product of the HTTP Working Group. The IESG contact persons are Gorry Fairhurst and Mike Bishop. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-httpbis-no-vary-search/ Technical Summary This specification defines an extension to HTTP Caching, changing how key=value pairs in the URI query fragment impact caching. Working Group Summary The input on this document has mainly been from a few (4-5) individuals who worked hard on reviewing caching aspects and consistency with other documents. This document originated as a W3C draft, and still carries some of the flavor of that background. A few participants felt that the name was too narrow to one particular use- case, which could hamper discoverability. This was ultimately set aside as a recurring bikeshed, as it does not impact the technical behavior. Document Quality There are at least two implementations in shipping web browsers, with additional implementation interest from others. Personnel The Document Shepherd for this document is Tommy Pauly. The Responsible Area Director is Mike Bishop. IANA Note This document registers a new field name in the Hypertext Transfer Protocol (HTTP) Field Name Registry (https://www.iana.org/assignments/http-fields/http-fields.xhtml)
