Abstract:
A method for adapting the operation of a computer program in a client-server environment, comprising the steps of:receiving at a server proxy associated with a data server a request from a client for a data document accessible by the data server; transmitting from the server proxy to a client proxy associated with the client a structure file, the structure file being representative of the data structure of the requested data document; applying at the client proxy a policy to the structure file, the application of the policy occurring on an automated basis and in the background relative to the perspective of the client and wherein the policy comprises a set of rules for identifying from the structure file a subset of the requested data document for retrieval; receiving from the data server, on the basis of the result of the application of the predetermined policy to the structure file, a subset of the requested data document; running the computer program using the subset of the requested data document; receiving at the client an additional subset of the requested data document, the content of the additional subset being determined according to the predetermined policy; and updating the data document with the additional subset of the requested data document; and wherein the step of running the computer program using a subset of the requested data document and the step of updating at the client the data document occur without modification to the source code of the computer program or the data document accessible by the data server.
