HTTP / 2 ready

Today, the specification of the new version of HTTP has become the final form. The chairman of the IETF HTTP working group, Mark Nottingham, wrote in his blog that the IESG formally approved the HTTP / 2 specifications. Now they are sent to the RFC editor , where they will be assigned the official RFC number, edited and published a little.



Soon this wonderful event will be reflected in the official IETF blog , but for now Mark Nottingham personally thanks everyone who contributed to the development of the new specifications. In particular - the developers of the protocol SPDY, which formed the basis of HTTP / 2.



Among the key features of the binary protocol HTTP / 2, which replaced the text HTTP / 1.1:

')

• Increase network resource utilization efficiency by multiplexing requests, prioritizing requests and compressing HTTP headers, proactive server-side push responses.
• Serious increase in performance for modern browsers and mobile devices.
• The ability to deploy on the modern Internet using IPv4 and IPv6, and not forgetting about NAT.
• Simplify the deployment of HTTP-based solutions.
• Providing modern security requirements.

HTTP / 2 is the most important innovation in the Hypertext Transfer Protocol since the release of HTTP / 1.1 in 1999.



You can test HTTP / 2 now. It is supported by Firefox and Chrome browsers (the setting is disabled by default, the protocol identifier is “h2-14”). There are several test servers from Akamai, Google and Twitter, as well as open source implementations.
