.NET Remotable Objects : Client-Activated Objects (CAO)

Client-activated objects (CAO) are server-side objects that are activated upon request from the client. When the client submits a request for a server object using a "new" operator, an activation request message is sent to the remote application. The server then creates an instance of the requested class, and returns an ObjRef back to the client application that invoked it. A proxy is then created on the client side using the ObjRef. The client's method calls will be executed on the proxy. Client-activated objects can store state information between method calls for its specific client, and not across different client objects. Each invocation of "new" returns a proxy to an independent instance of the server type.
