Re: I-D Action: draft-ietf-httpbis-connect-tcp-11.txt

Hi HTTPBIS,

As we discussed in yesterday(?)'s meeting, I've changed the text of "connect-tcp" to forbid Proxy-Status trailers instead of allowing them.  In draft-11, the sentence in question now reads:

> Clients and proxies MUST NOT send trailer fields on "connect-tcp" streams.

I avoided commentary on whether this is forbidden by RFC 9113 and RFC 9114, because it's not clear to me whether those requirements apply.  (They are arguably limited to non-Extended CONNECT.)  It is logical enough to forbid it here narrowly, even if it could be permitted.  (For example, forbidding trailers here makes "connect-tcp" more consistent across HTTP versions.)

I am not aware of any remaining issues that need to be addressed in this draft.

Internet-Draft draft-ietf-httpbis-connect-tcp-11.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-11.txt
   Pages:   17
   Dates:   2026-03-20

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.
