Method and system for tracking clients

A computer program stored on a computer readable medium for a client tracking system, including:

• a client tracking server object derived from a server class that provides an implementation of a query interface function wherein if the query interface function invokes a second function according to convention, then the second function is overridden, wherein a phantom server class that includes functions that correspond to the functions of the server class and that have the same signature as the corresponding function of the server class is provided;
• wherein a phantom manager class that includes a create function for instantiating a phantom server object of the phantom server class and returns a reference to the phantom server object is provided;
• wherein a client tracking server class that is a derivation of the server class wherein the query function of the client tracking server class invokes the create function of the phantom manager class is provided;
• wherein a client tracking Server object is instantiated;
• wherein the query function of the client tracking server object is invoked;
• wherein the query function invokes the create function of a phantom manager object which instantiates a phantom server object;
• wherein the query function returns a reference to the phantom server object.
