Google Chrome will adopt HTTP/2 in the coming weeks, drop SPDY support in early 2016
HTTP/2’s primary changes from HTTP/1.1 focus on improved performance. Some key features such as multiplexing, header compression, prioritization and protocol negotiation evolved from work done in an earlier open, but non-standard protocol named SPDY. Chrome has supported SPDY since Chrome 6, but since most of the benefits are present in HTTP/2, it’s time to say goodbye.
HTTP is an application protocol that forms the foundation of data communication for the World Wide Web. Over the years, it has become dated, and there have been many initiatives to speed it up. SPDY was one of them, but Google now admits it is no longer needed.
HTTP/2 will be the first new version of the HTTP protocol since HTTP 1.1, which was standardized back in June 1999. Google’s move should surprise no one given that HTTP/2, currently being developed by the Hypertext Transfer Protocol Bis (httpbis) working group of the Internet Engineering Task Force (IETF), is based on SPDY.
