Re: I-D Action: draft-ietf-httpbis-connect-tcp-10.txt

Hi HTTPBIS,

Apart from editorial improvements, revision 10 includes one significant change [1].  The essence of that change is:

1. For HTTP/1.1 over TLS implementations of CONNECT-TCP, relaxing the recommendation to send a TLS Error Alert to indicate TCP RST.  The new version has a broader recommendation that supports any closure other than a TLS Closure Alert (which could include an error alert, TCP FIN without TLS CloseNotify, or TCP RST).  This makes it easier to implement "RST after FIN" (i.e. abrupt shutdown in the half-closed state), which is somewhat esoteric anyway since it is hard to observe through the POSIX APIs.
2. Expanding the recommendation not to use HTTP/1.1 for CONNECT-TCP at all.  In the discussion of this PR, we identified several additional likely failure modes that can be avoided by using HTTP/2+.

I am not aware of any further changes needed in this draft.

Internet-Draft draft-ietf-httpbis-connect-tcp-10.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-10.txt
   Pages:   17
   Dates:   2025-12-05

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.
