HTTP (Hypertext Transfer Protocol) is one of the fundamental technologies behind the World Wide Web. However, HTTP was invented more than 20 years ago — and even the latest version, HTTP/1.1, is showing its age. Fortunately, developers have been working on HTTP/2, a next-generation version of HTTP that takes modern needs into account. HTTP/2 has taken a long time, but is nearly with us, and it is time to learn more about it. In this talk, HTTP/2 expert Mark Notthingham introduces the protocol, describes its benefits, and tells us what we can expect when we adopt HTTP/2.
