I'm afraid I have no idea what you're trying to say here - did you
actually read the message you're replying to? I described the HTTP
request/response procedure *without* persistent connections - they
didn't exist at "the initial success of the web", far less HTTP/1.1.
(Though it seems I was wrong about the request being terminated by
"simplex close" from the client, even if that would certainly have been
a possibility - but RFC 1945 effectively specifies server close as the
only reliable way to know when the response ends.)
