The Replication Server gateway also supports cascading connections, which allow your Replication Server to communicate with servers that it is not directly connected to. It also allows you to manage a replication domain using a single client connection. For example, you can connect to an ID Server, and then to the ID Server’s RSSD. In this case, both the primary, controlling Replication Server and the ID server are gateways; commands pass through to the ID server’s RSSD, and result sets pass back through to you.
