CloudFlare Enables HTTP/2 Server Push to Speed Website Delivery for Customers

CloudFlare has announced HTTP/2 Server Push support for all customers to speed up websites and mobile apps. HTTP/2 Server Push will be automatically enabled for free for CloudFlare’s four million customers.

Server Push enables the web servers to send content to website visitors without receiving requests. It allows images, fonts, CSS and JavaScript to be sent to the end user before the browser requests them, and CloudFlare estimates it gives a typical website a 15 percent performance increase.

Server Push is a fundamental update to HTTP/2, as it was not previously supported by the SPDY protocol it is based on, the company said. CloudFlare’s initial support for HTTP/2, which allows multiple HTTP requests over the same connection between a browser and web server, was announced in December.

“Usually, Internet performance improvements shave just milliseconds. In this case, the impact of HTTP/2 Server Push will be measured in seconds per page load, a quantum leap in performance that no service provider has been able to offer yet,” Matthew Prince, co-founder and CEO of CloudFlare said in a statement. “If with HTTP/2 Server Push we’re able to save one second off every page load served across CloudFlare’s network at our current scale, we would save about 10,000 years of time every day that people would have otherwise spent waiting for the Internet to load.”

HTTP/2 Server Push is currently in beta on Apple Safari, and is already supported in the latest versions of Chrome, Firefox, and Internet Explorer (Windows 10). CloudFlare is also providing an implementation guide for developers.

“HTTP/2 Server Push will enable a whole new class of web applications,” said CloudFlare CTO John Graham-Cumming. “It represents the biggest change in delivery of web content since AJAX–for the first time it gives web servers the power to send assets to a web browser. This upends the way in which the web works eliminating the need for countless browser performance hacks.”

CoudFlare launched a secure domain registrar business in February to appeal to high profile enterprises, and has been preparing to go public in more favorable market conditions, possibly in 2019.
