HTTP / 2 will appear in Chrome 40, SPDY support will be removed
In the official Chromium blog, project engineers report that in a few weeks Chrome 40 will receive support for the second version of the HTTP / 2 protocol, and SPDY support will be removed in early 2016. Support for the Next Protocol Negotiation NPN TLS-extension in favor of the newer ALPN (Application-Layer Protocol Negotiation) will also cease.
For the first time, SPDY appeared in Chrome 6 and was positioned by developers as a replacement for some parts of the HTTP protocol. After some time, in addition to the services of the search giant itself, the support of SPDY was implemented by such large sites Facebook and Twitter. Also SPDY began to support all popular browsers, including Internet Explorer. Although the testing of SPDY by Google engineers showed that the page load time was 36% less, it later turned out that with real sites, the page loading speed via HTTP and HTTPS does not reach the values that were claimed. The new HTTP / 2 largely repeats the ideas of SPDY.
Google recommends that server developers think about switching to HTTP / 2 and ALPN.
