DelegatedServer Class

Summary
Defines all of the properties needed to delegate a client's requests to another JPIP server.
Syntax
C#
C++/CLI
Python
public class DelegatedServer 
public ref class DelegatedServer  
class DelegatedServer: 
Remarks

You create an instance of this class with the properties you want and then you add it to the DelegatedServersCollection collection.

If multiple DelegatedServer are added into the DelegatedServersCollection collection the load is distributed based on a round-robin algorithm until each DelegatedServer receives its share.
