HTTP/2: History, Technology & Standards

HTTP/2 (originally named HTTP/2.0) is a major revision of the HTTP network protocol used by the World Wide Web. It was derived from the earlier experimental SPDY protocol, originally developed by Google. HTTP/2 was developed by the HTTP Working Group (also called httpbis, where "bis" means "twice" in Latin) of the Internet Engineering Task Force (IETF).…
