Only .NET and Java Open Clients can access an AppServer over an intranet, using an OpenEdge®-proprietary AppServer protocol to transport requests. For this type of connection, the Open Client interface maps to the application service in a "native mode" supported by the Open Client proxy using a connection that directly accesses the AppServer. As such, the interface to an AppServer, whether it is over the Internet or over the intranet, appears identical to the Open Client; only the protocol used to make the connection is different between the two.
