HTTP3
In plain terms
The latest HTTP version, built on the QUIC transport.
Going deeper
HTTP/3 runs over QUIC (on UDP) instead of TCP, reducing latency and avoiding head-of-line blocking for faster, more resilient connections. It speeds up the modern web.
Under the hood
QUIC integrates encryption and multiplexing, with faster handshakes and better behavior on lossy networks.
Examples
Modern browsers, QUIC, low-latency web, mobile networks, CDNs.
Think of it like...
Like upgrading from a single-file road to a smart multi-lane one that reroutes around jams.
