Ticket #25619 changed the default protocol to HTTP/1.1 but did not properly implement keep-alive. As a "fix" keep-alive was disabled in ticket #28440 to prevent clients from hanging (they expect the server to send more data if the connection is not closed and there is no content length set). The combination of those two fixes resulted in yet another problem: HTTP/1.1 by default allows a client to assume that keep-alive is supported unless the server disables it via 'Connection: close' -- see RFC2616 8.1.2.1 for details on persistent connection negotiation. Now if the client receives a response from Django without 'Connection: close' and immediately sends a new request (on the same tcp connection) before our server closes the tcp connection, it will error out at some point because the connection does get closed a few milli seconds later. This patch fixes the mentioned issues by always sending 'Connection: close' if we cannot determine a content length. The code is inefficient in the sense that it does not allow for persistent connections when chunked responses are used, but that should not really cause any problems (Django does not generate those) and it only affects the development server anyways. Refs #25619, #28440.
