WebSocket protocol

This directory contains the implementation of the WebSocket protocol.

Design docs

• WebSocketBasicHandshakeStream design memo. Some details have changed, but still a mostly-accurate description of Chromium's current implementation.
• WebSocket Throttling Design discusses how we enforce WebSocket connection throttling. Also contains detailed discussion of how WebSockets integrate with the socket pools. Dates from 2014, but still mostly relevant.
• WebSockets over HTTP/2. Current as of 2019 description of WebSocket over H/2 implementation.
• WebSocket + Network Service + WebRequest API: design for how extension callbacks are called when the network service is enabled.
• WebSocket HTTP Auth Design. This document is very low on detail, but can serve as an overview of how auth works for WebSockets.
• Per-renderer WebSocket throttling. While the algorithm described in this document is still used, the code has moved around significantly due to network servicification.
• WebSocket Protocol Stack in chrome/net. Early design doc for the current implementation. Mostly of historical interest only.
