US Patent 7966366 Dynamic postback for location code execution

Architecture that introduces evaluation and decisionmaking (e.g., at the server) and allows a runtime decision to be made, on a per-request basis, as to where the data calculations will occur, on the server, on the client, or as a shared execution on both the server and the client. The decision can be made based on environment variables (e.g., permissions, network bandwidth, server load, etc.) of the user, for example. This approach provides performance tuning of a form by dynamically optimizing the location of execution of the code based on environment factors.
