Re: I-D Action: draft-ietf-httpbis-connect-tcp-08.txt

I won't be attending IETF 123 in-person, but I've put together a basic implementation of connect-tcp for interop testing, in a fork of masque-go: https://github.com/bemasc/masque-go/tree/capsules.

Please reach out during the hackathon if you have a chance to try it with your implementation.

Great, thanks. I'll plan to have an implementation for the Madrid hackathon if anyone wants to interoperate. David On Wed, Jun 11, 2025 at 7: 08 PM Ben Schwartz <bemasc@ meta. com> wrote: I agree, -08 should be a good interop target.

Hi Ben, Thanks for landing these changes. I think now sounds like a good time to work on interop for connect-tcp. Should we declare draft -08 the interop target? Or do you have compatibility-breaking changes planned that we should wait for?

Hi HTTPBIS,

This revision of connect-tcp adds FINAL_DATA, a new capsule type to ensure a clear distinction between clean and abrupt termination of TCP sessions.  It includes a fully specified shutdown sequence that avoids losing information without requiring extreme specification complexity or implementation heroics.

Thanks to everyone who participated in the extensive design discussions [2]

Internet-Draft draft-ietf-httpbis-connect-tcp-08.txt is now available. It is a
work item of the HTTP (HTTPBIS) WG of the IETF.

   Title:   Template-Driven HTTP CONNECT Proxying for TCP
   Author:  Benjamin M. Schwartz
   Name:    draft-ietf-httpbis-connect-tcp-08.txt
   Pages:   17
   Dates:   2025-06-11

Abstract:

   TCP proxying using HTTP CONNECT has long been part of the core HTTP
   specification.  However, this proxying functionality has several
   important deficiencies in modern HTTP environments.  This
   specification defines an alternative HTTP proxy service configuration
   for TCP connections.  This configuration is described by a URI
   Template, similar to the CONNECT-UDP and CONNECT-IP protocols.
