HTTP/3 is the third major version of the Hypertext Transfer Protocol used to exchange information on the World Wide Web, complementing the widely deployed HTTP/1.1 and HTTP/2. Unlike previous versions which relied on the well-established TCP (published in 1974), HTTP/3 uses QUIC (officially introduced in 2021), a multiplexed transport protocol built on UDP.

HTTP/3是第三个主要版本的HTTP协议。与其前任HTTP/1.1和HTTP/2不同,在HTTP/3中,将弃用TCP协议,改为使用基于UDP协议的QUIC协议实现。 此变化主要为了解决HTTP/2中存在的队头阻塞问题。由于HTTP/2在单个TCP连接上使用了多路复用,受到TCP拥塞控制的影响,少量的丢包就可能导致整个TCP连接上的所有流被阻塞。 QUIC(快速UDP网络连接)是一种实验性的网络传输协议,由Google开发,该协议旨在使网页传输更快。在2018年10月28日的邮件列表讨论中,互联网工程任务组(IETF) HTTP和QUIC工作组主席提出了将HTTP-over-QUIC更名为HTTP/3的正式请求,以“明确地将其标识为HTTP语义的另一个绑定……使人们理解它与QUIC的不同”,并在最终确定并发布草案后,将QUIC工作组继承到HTTP工作组。 在随后的几天讨论中,的提议得到了IETF成员的接受,他们在2018年11月给出了官方批准,认可HTTP-over-QUIC成为HTTP/3。 2019年9月,HTTP/3支持已添加到Cloudflare和Google Chrome(Canary build)。Firefox Nightly在2019年秋季之后添加支持。 2022年6月6日,IETF正式标准化HTTP/3为RFC9114。
