As we know, the World Wide Web was invented by Sir Tim Bernes-Lee in the 1980s. He also contributed in developing HTTP 1.1. HTTP is hyper-text transfer protocol. This versionwas developed in 1999. After 16 years it is being upgraded to HTTP 2.0 The Working Group under the aegis of Internet Engineering Task Force has worked on HTTP 2.0 This version will have two closely spaced protocols — HTTP 2.0 and HPACK for headers.

HTTP 2.0  will be introduced in the browsers soon to improve dramatically the speed of page loading with connections lasting longer and server responsiveness being better. HTTP 1.1 sent out more page requests resulting into congestion in network and duplication of data.In other words it made the browser work harder.HTTP 2.0 overcomes this to accelerate the speed and reduce the latency.HTTP 1.1 had multiple connections approach, whereas HTTP 2.0 avoids it.

HTTP 2.0 mimics Google’s SPDY protocol and Google Chrome proposes to abandon SPDY in favour of HTTP 2.0.HTTP 2.0 does not support Transport Layer Security or TLS which is for privacy and security. HTTP 2.0 keeps this optional. Consumers can opt for it or can use the old TCP.

HTTP 2.0 is compatible with both HTTP 1.0 and HTTP 1.1. Chrome and Firefox 39 will be supporting HTTP 2.0 Windows 10 has made an early build document draft 14 in its technical preview.
