This property allows you to specify a list of failover hosts in addition to the one configured in Server and Port .
Specify both a server and port with multiple values separated with commas. For example 'server1:port1,server2,port2'.
The Server and Port values take precedence and will be used to make the initial connection. Upon a failure to connect to the main host, the list of FailoverHosts will be used to attempt the connection.
