Re: [jetty-users] Server Hint vs Server Push

[Guillaume Drouet <guidrouet@xxxxxxxxx>]

Thanks that was exactly what I was thinking about actually. But, in that case, we never use server-push, right? Choosing between server-hints and server-push should be a decision driven by per-application benchmark?

I did not say that a hint is preferred to a primary resource.

What I mean by:

GET /primary.html HTTP/2
HTTP2-Push: hint

is the client telling the server: "GET me /primary.html. If it happens
that primary.html has associated resources that you can push, then
please don't push them to me, but send me back hints in the form of
Link headers".
The response would be:

HTTP/2 200
Link: </css/styles.css>; rel=prefetch
Link: </js/jquery.js>; rel=prefetch
Link: </css/background.png>; rel=prefetch
Content-Length: 65536
Content-Type: text/html; charset=UTF-8
...

The client would receive the headers, parse them, and can prefetch the
resources (or look at its cache) before it actually receives the HTML
content that defines those resources.

If the server sends, for example, etag information in the Link header,
the client may do even more precise decisions.
