HTTP/3 (QUIC)

HTTP/1 vs HTTP/2 vs HTTP/3 - DEV Community

HTTP/2 is coupled to TCP features, HTTP/3 reimplemented HTTP/2 features on top of QUIC, a UDP-based protocol

QUIC itself reimplements most TCP features on top of UDP, and deeply integrates TLS
This makes most of the payload opaque to firewalls so they won't mess up the packet

Server Push is deprecated, use 103 Early Hints instead.
