Management of configurable applications programs on a network is provided by using two program files for each configurable application program. The two program files are provided to a network server station which operates as the on-demand server for software deployment and may also act as the application server. The on-demand server makes the first (configuration manager) program available to an administrator to obtain preferences for the configurable preferences of the application program which have been designated as administrator preferences. The on-demand server also provides a second (application launcher) program to its client stations. The application launcher program not only provides for a user interface to execute the application program itself but also allows a user to specify one or more of the configurable parameters of the application program. An icon is displayed on the screen of the client station through which a user may initiate execution of the application program. The application launcher program provides the identity of the user to the server along with the request to initiate execution of the application program. The on-demand server then initiates execution of the application program using stored values for the user and administrator set preferences or, if no preferences have yet been obtained for the particular user, obtains user preferences before initiating execution of the application program.

The system of claim 49 in which an identified inconsistency between the first order-sensitive checksum value and the second order-sensitive checksum value determines that the client should not continue processing the previously accessed data transmitted from the first server node.51. The system of claim 50 in which a query data set from the second server node is retransmitted to the client after the inconsistency is identified.52. The system of claim 44 in which the order-sensitive checksum is not transmitted if the previously accessed data has not changed.53. The system of claim 44 in which the scrollable cursor on the client utilizes information fetched from the resource.54. The system of claim 44 in which the previously accessed data transmitted from the first server node is fully or partially cached at the client.55. A computer program product that includes a computer readable medium, the computer readable medium comprising instructions which, when executed by a processor, causes the processor to execute a process for recovering after failure of a first server to which a client was connected for accessing a resource, the process comprising: detecting that a connection between the first server and the client has failed;automatically connecting the client with a second server that has access to the resource; andaccessing the resource through the second server, wherein an order-sensitive checksum is employed to verify usability of the resource.56. The computer program product of claim 55 in which the following is employed to calculate the order-sensitive checksum (Co):Initially Co=0When adding rows x . . . y to existing cache with rows1 . . . (x−1)For (row i from x . . . y)Co=checksum_function(Co, column values of row i).57. The computer program product of claim 55, wherein the process further comprises comparing a first order-sensitive checksum value with a second order-sensi
