Hi, I've just posted a new I-D named "An HTTP Status Code for Indicating Hints". The draft can be found at https://datatracker.ietf.org/doc/draft-kazuho-early-hints-status-code/ A prettified editor's copy can be found at https://kazuho.github.io/early-hints/ The draft proposes a new _informational_ status code that can be used for indicating hints to help a client start making preparations for processing the final response, while the server struggles to build the final response. Actually, we already have a working implementation. H2O, our HTTP/2 server, recognizes Link: rel=preload headers within an informational response sent from upstream, and tries to push the specified resource. One reason I decided to write this draft is because I believe it would be better to standardize the mechanism. But I also believe that having support for this status code within the web browsers is beneficial as well. For example, the proposed status code can be used by edge servers to notify the client the existence of third-party resources while the request is processed by an upstream server. It can also be used as an alternative to H2 push on a bandwidth-constrained network. In short, I consider the proposed method as a good complement to H2 push. Please let me know what you think. Thank you in advance. ---------- Forwarded message ---------- From: <internet-drafts@ietf.org> Date: 2016-10-31 23:09 GMT+09:00 Subject: New Version Notification for draft-kazuho-early-hints-status-code-00.txt To: Kazuho Oku <kazuhooku@gmail.com> A new version of I-D, draft-kazuho-early-hints-status-code-00.txt has been successfully submitted by Kazuho Oku and posted to the IETF repository.
