HTTP/2 revolutionizes the web by making better use of network resources. Version 2.0 is a major overhaul of the HTTP protocol, which forms the backbone of the World Wide Web. Thanks to the improvements and optimizations it brings, it improves the performance and efficiency of the internet.
Furthermore, with HTTP version 2.0, servers send you the resources you need before you ask for them, such as images or files. All these improvements work together for faster web performance and a silky-smooth online experience.
According to RFC-7540 from the Internet Engineering Task Force (IETF), HTTP/2 enables more efficient use of network resources and reduces the perception of network latency by
introducing header field compression
enabling multiple simultaneous exchanges on the same connection
enabling flow control and stream prioritization
introducing unsolicited push of representations from servers to clients.
