<p>After loading the page, the plugin starts to follow the user’s screen. And as soon as a link appears on the screen within your site – the browser executes the request and downloads it. Now that the user clicks on the link, the browser will instantly display a new cache page. Thus, User Experience will indicate that your site is loading instantly.</p>
<h3>How it work</h3>
<p>The plugin uses the built-in browser features to predict user behavior for preloading the tourniquet. See <a href="https://en.wikipedia.org/wiki/Link_prefetching" title="Link prefetching" rel="nofollow ugc">this</a></p>
<h3>API</h3>
<p>The plugin also registers a global feature that you can use to preload any URL:</p>
<pre><code>window.prefetch('https://example.com/custom/page')
</code></pre>


Prefetch visible links

Preloads the page before the visitor clicks on the link.

<p>HTTP/2 is the new generation of the venerable HTTP protocol that powers the web. Among its most powerful features is <em>server push</em>, 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.</p>
<p>This plugin enables WordPress to send a <code>Link:<...> rel="prefetch"</code> 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.</p>
<p>Requires a web server that supports HTTP/2.</p>
<h3>WordPress 4.6 and above</h3>
<p>WordPress 4.6 introduced <a href="https://make.wordpress.org/core/2016/07/06/resource-hints-in-4-6/" rel="nofollow ugc">native support for resource hints</a>.<br />
By default, this plugin defers to WordPress 4.6 and theme/plugin developers to responsibly prefetch the right assets. Sites running<br />
on older versions of WordPress will continue to get the previous behavior where all JavaScript and stylesheets had resource hints<br />
printed for them.</p>
<p>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<br />
your theme’s functions.php file or a custom plugin:</p>
<pre><code>`add_filter('http2_render_resource_hints', '__return_true');```
</code></pre>


HTTP/2 Server Push

This plugin helped speed up my website by 33%!

Works as advertised

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

Speeds things up

Works perfectly in conjunction with Cloudflare to deliver excellent performance

Works perfectly

Enables HTTP/2 server push for local JavaScript and CSS resources.
