HTTP/2 Server Push

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.
