 ### Failover Configuration options
 With failover enabled the client can reconnect to another server automatically when connection to the current server is lost for some reason. The failover URI is always initiated with the failover prefix and a list of URIs for the server(s) is contained inside a set of parentheses. The "nms." options are applied to the overall failover URI, outside the parentheses, and affect the NMS Connection object for its lifetime.
