The Internet waited decades for an upgrade to HTTP/1. But several features of HTTP/2 have proved problematic, and now just six years after its introduction, HTTP/3 has come on the scene along with a brand new transport protocol, QUIC.
In this video, we review the history of HTTP, explain how HTTP/3 fixes problems with HTTP/2 and introduces new challenges, and discuss the NGINX implementation of QUIC and HTTP/3.
You can find the NGINX and QUIC demo site at quic.nginx.org
