SEMANTICS describes CONNECT in HTTP/1.1 terms

[MikeBishop]

I think the goal was for SEMANTICS to stay out of message framing and leave that to the individual mappings. It currently says this about CONNECT:

Any 2xx (Successful) response indicates that the sender (and all inbound proxies) will switch to tunnel mode immediately after the blank line that concludes the successful response's header section; data received after that blank line is from the server identified by the request target.

Perhaps this should simply talk about data received after the header section, and leave the boundaries of that version-specific?

Yes, we just missed a spot. Willy noticed this one as well. It should be something like

Any 2xx (Successful) response indicates that the sender (and all inbound proxies) will switch to tunnel mode immediately after the response's header section; data received after the header section is from the server identified by the request target.

Yes, I wanted to suggest "header section" as well as it's the term used in messaging. There is a second occurrence of this one in "15.2.2 - 101 Switching Protocols" : "will be switched to immediately after the empty line that terminates the 101 response".
