About HTTP/2 Server Push
From the official readme · v1.4Description
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.
Requires a web server that supports 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');```
Installation
Install HTTP/2 Server Push automatically from your admin account by selecting “Plugins”, then “Add new” from the sidebar menu. Search for HTTP/2 Server Push, then choose “Install Now”.
or
Download the latest HTTP/2 Server Push plugin archive from wordpress.org. Unzip the archive and upload the http2_server_push directory to the /wp-content/plugins/ directory on your WordPress site. Activate the plugin through the ‘Plugins’ menu in WordPress
Changelog
WordPress 4.6 introduced native support for resource hints and this plugin no longer generates them. To restore the old behavior (hint everything) on WordPress 4.6 and above, add this line to your theme's functions.php file or a custom plugin: `add_filter('http2_render_resource_hints', '__return_true');```
