Proxying UDP in HTTP
Overview
RFC 9298, “Proxying UDP in HTTP”, is a Proposed Standard document published in August 2022 by D. Schinazi. It has since been updated by RFC 9484, RFC 9931. The canonical text is published by the RFC Editor.
Abstract
This document describes how to proxy UDP in HTTP, similar to how the HTTP CONNECT method allows proxying TCP in HTTP. More specifically, this document defines a protocol that allows an HTTP client to create a tunnel for UDP communications through an HTTP server that acts as a proxy.
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.
