Server Object Extensions allow developers to extend the functionality of server objects in ArcGIS Server through custom .NET classes. These extensions live and die with their associated server object, helping to minimize remote ArcObjects calls and cache data, improving performance compared to using raw ArcObjects or SOAP APIs. Extensions can add new properties and methods that are then available through the various ArcGIS Server APIs like the Web ADF.
