Bootstrapping WebSockets with HTTP/3
Overview
RFC 9220, “Bootstrapping WebSockets with HTTP/3”, is a Proposed Standard document published in June 2022 by R. Hamilton. The canonical text is published by the RFC Editor.
Abstract
The mechanism for running the WebSocket Protocol over a single stream of an HTTP/2 connection is equally applicable to HTTP/3, but the HTTP-version-specific details need to be specified. This document describes how the mechanism is adapted for HTTP/3.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
