Comment 1 for bug 1947010

1st example: if a second request is 6 seconds after the first request (> KeepAliveTimeout=5), tcp connection is not reused under keystoneauth1.session.Session.

The line to highlight is "urllib3.connectionpool:Resetting dropped connection" which is resetting the TCP connection and to re-establish another TCP connection.
