About HTTP/3
HTTP/3 is the third major version of the Hypertext Transfer Protocol, standardized in RFC 9114. It is built on QUIC, a multiplexed transport protocol over UDP, replacing the TCP foundation used by HTTP/1.1 and HTTP/2. HTTP/3 offers improved connection establishment speed, reduced head-of-line blocking, and better performance on lossy networks.
HTTP/3 is supported by major browsers including Chrome, Firefox, and Safari, and by CDN and server providers such as Cloudflare, Nginx, and Caddy. Its adoption has grown rapidly since its standardization, particularly for latency-sensitive applications and mobile users on variable network conditions.
