HTTP/2 Server Push

Περιγραφή

HTTP/2 is the new generation of the venerable HTTP protocol that powers the web. Among its most powerful features is server push, a way for web servers to send resources to the browser before it even realizes it needs them. This avoids the usual HTTP request/response cycle which happened for every script or stylesheet on a page.

This plugin enables WordPress to send a Link:<...> rel="prefetch" header for every enqueued script and style as WordPress outputs them into the page source. Unfortunately, it can’t help plugins and themes that output their scripts directly into the page itself, but these will continue to work as they always have.

Απαιτείται εξυπηρετητής web που υποστηρίζει HTTP/2.

WordPress 4.6 and above

WordPress 4.6 introduced native support for resource hints.
By default, this plugin defers to WordPress 4.6 and theme/plugin developers to responsibly prefetch the right assets. Sites running
on older versions of WordPress will continue to get the previous behavior where all JavaScript and stylesheets had resource hints
printed for them.

I’ve added a filter To restore the old behavior (hint everything) on WordPress 4.6 and above. To use it, add this line to
your theme’s functions.php file or a custom plugin:

`add_filter('http2_render_resource_hints', '__return_true');```

What if my web server doesn’t support HTTP/2 or «server push»?

Server push is triggered by the same mechanism as link prefetching, which almost all major modern browsers support over HTTP 1.x. So even if you can’t take advantage of HTTP/2’s features, people visiting your site may still get a better experience from prefetching.

Πως ξέρω αν αυτό δουλεύει;

Υπάρχουν δύο τρόποι:

  1. nghttp is an HTTP/2 client that ships with the nghttp2 suite. nghttp -v http://example.com will show all the HTTP/2 signalling packets, HTTP headers, content, and resources sent from the server in a single request. You can see PUSH PROMISE signals from the server and the pushed resources after the main page is sent.
  2. In Google Chrome, chrome://net-internals/#spdy will show a history of server connections from the browser. Clicking on a connection will show the discussion between the browser and the server. Within that text, you can see PUSH PROMISE packets and the pushed resources.

This plugin does just what it says it'll do, HTTP/2 pushes everything! That generally will speed things up unless you have a ridiculous number of assets. While it now respects resource hinting for themes and plugins that provide that info, I do wish it had a UI for older themes/plugins to control what assets were going to be pushed instead of pushing them all. This plugin is so great without that though it still gets 5 stars
