Hi Mike,

What category do you think something like DNS over HTTPS falls into? In this case, DNS could be pushed using the the GET method format. This is related to the DOM but doesn't deliver a resource that is explicilty part of the render.

Subject: Push Use Cases

This draft isn't targeted for a protocol standard so much as enumerating different ways to use push.  HTTP/2 provides the mechanics of pushing a request/response pair that the client hasn't asked for yet, but... what exactly does that request look like, and what does a client actually *do* with it?

Pretty much the only thing that has coalesced is dependent resources on the same page.  Pushing responses to XHR queries, pushing cache validation updates or invalidations, etc. are things that we've handwaved about and never really defined.

This draft is an effort to enumerate the different ways that push *could* be used, in hopes that it can develop into a common reference to describe what each client supports or doesn't.

Abstract:
   HTTP/2 defines the wire mechanics of Server Push.  Though the
   mechanics of how a pushed resource is delivered are well-specified,
   the use cases that describe which resources can be pushed, in what
   states, and for what purpose are not described in HTTP/2.  As a
   result, support between implementations varies widely.

   This document attempts to enumerate interesting scenarios, in hopes
   that a more concrete taxonomy can assist the community in arriving at
   a standard set of supported scenarios.




Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
