Abstract: In a data processing environment where a client requests a server to perform part of its processing, a method of updating the client's version of server-related data without requiring the client to be a server, includes steps of: receiving, at a control point server, a first request from the client requesting that server-related data be transferred from the control point server to the client; and in response to the first request, sending the server-related data from the control point server to the client, along with a unique bind token identifying a version number of the server-related data such that each time the server-related data changes a new unique bind token is associated with the data, where the client uses the server-related data to form a second request for the server to perform part of the client's processing, and where the client sends said bind token to the server as part of the second request.
