Introduction

Site Performance, Performance, Site speed

HTTP/2 Push is a feature of the latest HTTP revision that enables the web server to preemptively send resources to the requesting client before the client knows that they are needed. As a result, the number of round-trips that are required to fully load a web page may be reduced, resulting in a potentially large performance boost (especially on slow cellular networks).

Implementation Details

This project is a system plugin for Joomla! that intercepts the onAfterRender event. Once the event is triggered, the plugin parses the HTTP response body to find any applicable resources that can be configured for preload or preconnect.

The plugin then sets a Link header to inform the web server about the resulting resources. Once the web server is made aware, all (or some) of the resources are pushed to the client.
