+
+HTTPConnection go through a number of "states", which defines when a client
+may legally make another request or fetch the response for a particular
+request. This diagram details these state transitions:
+
+ (null)
+ |
+ | HTTPConnection()
+ v
+ Idle
+ |
+ | putrequest()
+ v
+ Request-started
+ |
+ | ( putheader() )* endheaders()
+ v
+ Request-sent
+ |
+ | response = getresponse()
+ v
+ Unread-response [Response-headers-read]
+ |\____________________
+ | |
+ | response.read() | putrequest()
+ v v
+ Idle Req-started-unread-response
+ ______/|
+ / |
+ response.read() | | ( putheader() )* endheaders()
+ v v
+ Request-started Req-sent-unread-response
+ |
+ | response.read()
+ v
+ Request-sent
+
+This diagram presents the following rules:
+ -- a second request may not be started until {response-headers-read}
+ -- a response [object] cannot be retrieved until {request-sent}
+ -- there is no differentiation between an unread response body and a
+ partially read response body
+
+Note: this enforcement is applied by the HTTPConnection class. The
+ HTTPResponse class does not enforce this state machine, which
+ implies sophisticated clients may accelerate the request/response
+ pipeline. Caution should be taken, though: accelerating the states
+ beyond the above pattern may imply knowledge of the server's
+ connection-close behavior for certain requests. For example, it
+ is impossible to tell whether the server will close the connection
+ UNTIL the response headers have been read; this means that further
+ requests cannot be placed into the pipeline until it is known that
+ the server will NOT be closing the connection.
