The IESG has approved the following document: - 'Prefer Header for HTTP' (draft-snell-http-prefer-18.txt) as Proposed Standard This document has been reviewed in the IETF but is not the product of an IETF Working Group. The IESG contact person is Barry Leiba. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-snell-http-prefer/ Technical Summary This specification defines an HTTP header field that can be used by a client to request that certain behaviors be implemented by a server while processing a request. Working Group Summary This is not a Working Group document, but it has been discussed extensively on the HTTPbis WG mailing list, and has had an informal Last Call there. There seems to be broad consensus to publish it, and no significant issues remain. Document Quality Implementation is forthcoming in Apache Abdera, and this specification is referenced by Microsoft's OData protocol. Other non-public implementations have been discussed but not disclosed. It has gone under substantial review and change based upon that review. It is expected that this mechanism will be used mostly by "API" applications of HTTP, rather than in Web browsers, so HTTP implementations per se don't need to support it specifically. Personnel Mark Nottingham is the Document Shepherd. Barry Leiba is the Responsible Area Director.
