Hi all,

David and I recently revised the QUIC-aware proxying draft (which adds the ability to share sockets and perform forwarding on top of CONNECT-UDP).

This new revision aligns with the latest CONNECT-UDP and HTTP datagram drafts by adopting capsules and using CONNECT-UDP’s extended CONNECT method.

We ended up not needing to use any context IDs (as defined in HTTP datagrams), but instead are just using some new capsule messages to add control signaling between the client and the proxy. Hopefully, this informs some of our broader discussion about how the extensibility provided by HTTP datagrams can be used, and which parts are most useful.

Best,
Tommy

> Abstract:
>   This document defines an extension to UDP Proxying over HTTP that
>   adds specific optimizations for proxied QUIC connections.  This
>   extension allows a proxy to reuse UDP 4-tuples for multiple
>   connections.  It also defines a mode of proxying in which QUIC short
>   header packets can be forwarded using an HTTP/3 proxy rather than
>   being re-encapsulated and re-encrypted.
