* --------------------------------------------------------------------------
* 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.
