# High Performance Browser Networking

Grigorik's O'Reilly book on what actually happens between the browser and the network: TCP, TLS, HTTP/1.1 vs HTTP/2, WebSockets, WebRTC, mobile radios. Free to read at [hpbn.co](https://hpbn.co/). Dated on HTTP/3 / QUIC but the protocol-mechanics chapters still hold. On the [[eatonphil-bookclub]] speculative future list.
