*  Note: The above REST connection and setup of the AWS credentials
*  can be done once.  After connecting, any number of REST calls can be made.
*  The "auto reconnect" property passed to rest.Connect indicates that if
*  the connection is lost, a REST method call will automatically reconnect
*  if needed.
