Changes
(cherry picked from commit 7a9a85b)
Disable keep alive forces the HTTP client to drop the connection
once a response is received. This avoids building up large numbers
of idle connections and it fixes the immediate issue.
After this we may want to see how to ensure we can re-use connection
and also set and idle-connection timeout.
