A method, apparatus, computer program product, and computer system for ensuring consistency between data displayed by multiple independent client programs that can simultaneously display server-provided data. The data are accessible only from a server that is not persistently connected to the client computer systems) displaying the data, so the client programs cannot retrieve the data independently without sending a request to the server. Client programs do not poll the server by sending a request to learn that data capable of being displayed by the multiple client programs have been updated. Instead, client programs are notified by the server program receiving the request to change the data at the time the request is received.
