This leads me to my next question: What is the transition sequence for the cases in which an HTTP/1.1 client that normally uses chunking wants to make a request of a server that is HTTP/1.0 and/or doesn't understand chunking?
Does this scenario look correct?:
1. Client requests HTTP/1.1, Transfer-Encoding: chunked
2. Server responds HTTP/1.0 501 (Unimplemented), and closes the connection
3. Client opens new connection and requests HTTP/1.0, Content-Length
Also, don't some HTTP/1.0 implementations understand Transfer-Encoding as an extension? We have some client situations where we can't avoid chunking, so it would be nice if even the HTTP/1.0 servers understood chunked transfer coding. (Presumably all HTTP/1.1 applications are able to receive and decode the “chunked” transfer coding.)
