EuroPython 2022 - How I wrote a Python client for HTTP/3 proxies - presented by Miloslav Pojman

While working on the proxy at Akamai, I wrote a Python client for testing the proxy service. The MASQUE protocol can tunnel traffic through HTTP/3 or HTTP/2, but common Python libraries only support HTTP/1.1. The tunneled traffic can use any protocol on top of TCP or UDP, including all HTTP versions, so MASQUE can be proxied through MASQUE for onion routing.

In this talk, I will show that the MASQUE proxy design is simple and yet client implementations are complex. To put everything into context, I will recap how HTTP proxies operate and how HTTP versions differ. I will highlight lessons learned from designing a low-level HTTP client using Python asyncio.
