HTTP/2

HTTP/2 is an update to Hypertext Transfer Protocol (HTTP), the application protocol that standardizes communication on the World Wide Web. In HTTP/2, the maintainers, Internet Engineering Task Force (IETF), have advanced many aspects of the HTTP protocol. HTTP/2 includes many updates to improve HTTP's flexibility and efficiency, enabling more robust web applications that load faster. One major feature of HTTP/2 is multiplexing, which allows multiple requests to be sent simultaneously, and enables asynchronous file downloads. HTTP/2 also introduced header compression. Whereas HTTP 1.1 was a text protocol, HTTP/2 is a binary protocol. At a high level, HTTP/2 is backward compatible with HTTP 1.1.
