HTTP/1.0 keep-alive can not be enabled unless the request explicitly says this is understood by the requestor. HTTP/1.1 alone does not imply that the requestor implements HTTP/1.1 keep-alive as the signaling methods of HTTP/1.1
I obviously meant to say "requestor implements HTTP/1.0 keep-alive ..."
and HTTP/1.0 keep-alive is quite different. The HTTP/1.0 keep-alive was never accepted into any standard, and can not be assumed to be understood unless signalled.
