HTTP/3 is a major overhaul of HTTP with performance and security in mind. It uses QUIC as a transport (our HTTP server, http.sys, is using msquic) to gain the benefits of eliminated head of line blocking at the transport layer. This is a significant improvement over HTTP/2 which eliminated head of line blocking only at the HTTP layer with streams that allowed a single HTTP/2 connection to replace a set of HTTP/1.1 connections. HTTP/3 also benefits from many lessons learned in HTTP/2, such as simplifying the protocol by removing prioritization. Please vist HTTP/3 - Wikipedia for more information on HTTP/3 |
