Abstract:
1. A method of providing information to a client device comprising: receiving, at a server, a status request from a client device; determining, at said server, a default refresh interval; determining, at said server, a number of clients due for a refresh within a predetermined time interval, the predetermined time interval including the expiration of the default refresh interval; setting, at said server, a refresh interval based on the default refresh interval, if the number of clients due for a refresh within the predetermined time interval is not greater than a maximum value; determining, at said server, an adjusted refresh interval, if the number of clients due for a refresh within the predetermined time interval is greater than the maximum value; setting, at said server, the refresh interval for at least a portion of the clients based on the adjusted refresh interval, if the number of clients due for a refresh within the predetermined time interval is greater than the maximum value, wherein setting the refresh interval based on the adjusted refresh interval results in the number of clients due for a refresh to be less than the maximum value within the predetermined time interval; and communicating status information to the client device in response to the status request, wherein the status information specifies the refresh interval.
