HTTP/3 becomes a standard
More than three years after it was first proposed, the third major version of the Hypertext Transfer Protocol, HTTP, has been adopted as an Internet Engineering Task Force (IETF) standard.
The QUIC transport protocol has several features that are desirable in a transport for HTTP, such as stream multiplexing, per-stream flow control, and low-latency connection establishment. This document describes a mapping of HTTP semantics over QUIC. This document also identifies HTTP/2 features that are subsumed by QUIC and describes how HTTP/2 extensions can be ported to HTTP/3.
