Abstract

A client/server computer system comprising: a communication link; a plurality of server computers including a dual-role proxy server computer connected to the communication link; a storage device connected to the communication link for storing information; and at least one client computer connected to the communication link. The client computer generates requests to the proxy server computer for processing certain information on the storage device. In response, the proxy server computer accesses said information on the storage device and associates program instructions to the information for processing the information. Thereafter, the proxy server computer processes the information according to the program instructions.

Claims

1. A client/server computer system, comprising:

a communication link;

at least one server computer connected to said communication link, wherein said server computer comprises a dual-role proxy server computer;

a storage device for storing information thereon, wherein said storage device is connected with said communication link; and

at least one client computer connected with said communication link, said client computer generating requests to said proxy server computer for processing certain information on said storage device, said proxy server computer accessing said information on said storage device and associating program instructions to said information on said storage device for processing said information on said storage device, wherein said proxy server computer processes said information on said storage device according to said program instructions;

wherein said at least one client computer includes a user interface module for;

allowing a user to select said information on said data storage device and to specify a type of processing for said information on said storage device; and

generating a request to said proxy server computer, said request including data identifying said information on said storage device and said type of processing specified by said user; and

wherein said proxy server computer processes said information on said storage device without needing said user to again locate said information on said storage device.

2. The system of claim 1, wherein said requests are generated by said client computer when said client computer is determined to be incompatible with said information on said storage device.

3. The system of claim 1, wherein said requests can be generated by said client computer even when said client computer can process said information on said storage device.

4. The system of claim 1, wherein said user interface module comprises a graphical user interface (GUI) having a dialog box, said dialog box comprising a first area for providing user directions and a second area for configuring said proxy server.

5. The system of claim 1, wherein said data identifying said information further comprise data to locate said information on said storage device.

6. The system of claim 5, wherein said storage device comprises a local storage device connected with said client computer, wherein said local storage device is only connected with said communication link through said client computer, and wherein said information on said storage device is stored on said local storage device.

7. The system of claim 1, wherein said proxy server computer includes an association module for selecting said program instructions appropriate for processing said information on said storage device and an access module for locating and accessing said information on said storage device based on said data identifying said information.

8. The system of claim 1, wherein said communication link comprises a local network.

9. The system of claim 1, wherein:

said at least one server computer includes a plurality of proxy server computers connected to said communication link; and

said at least one client computer generates one or more requests to at least one of said plurality of proxy server computers, each request being directed to a proxy server computer for processing a selected information on said storage device, said proxy server computer accessing said selected information and associating a selected program instruction to said selected information for processing said selected information, wherein said proxy server computer processes said selected information according to said selected program instruction;

wherein said at least one client computer includes a user interface module for;

allowing a user to select said information, to specify a type of processing for said selected information, and to specify a proxy server computer; and

generating a request to said specified proxy server computer, said request including data identifying said selected information and said type of processing specified by said user.

10. The system of claim 1, wherein said proxy server computer includes a processing platform for processing said information on said storage device.

11. The system of claim 10, wherein said processing platform comprises an operating system appropriate for operating said program instructions and wherein said program instructions are appropriate for processing said information on said storage device.

12. The system of claim 11, wherein said at least one client computer includes a second processing platform having a second operating system.

13. The system of claim 12, wherein said second operating system is incompatible with said information on said storage device.

14. The system of claim 1, wherein said at least one client computer includes an operating system and wherein said program instruction is designed for operating on a second operating system.

15. The system of claim 14, wherein said proxy server computer emulates said second operating system for said client computer.

16. A method for data processing by proxy comprising:

selecting a data file on a storage device via a client computer;

specifying a desired processing operation on said selected data file via said client computer;

specifying a proxy server computer for performing said desired operation on said selected data file via said client computer;

generating a request to said proxy server computer via said proxy server computer, wherein said request includes data identifying said desired operation;

transmitting said request from said client computer to said proxy server computer via a local network;

receiving said request by said proxy server;

associating program instructions appropriate for processing said selected data file on a processing platform of said proxy server computer, wherein said proxy server computer is configured with said processing platform and wherein said processing platform includes an operating system and said program instructions; and

launching said program instruction at said proxy server to process said selected data file, without needing a user to again select said selected data file on said proxy server.

17. The method of claim 16, wherein said specifying said proxy server computer occurs when said client computer is not capable of performing said desired processing operation.

18. A client/server computer system, comprising:

a local network;

at least one server computer connected with said communication link;

a storage device for storing information thereon, wherein said storage device is connected with said communication link; and

at least one client computer connected with said communication link, said client computer generating requests to said proxy server computer for processing certain information on said storage device, said proxy server computer accessing said information on said storage device and associating program instructions to said information on said storage device for processing said information on said storage device, wherein said proxy server computer emulates a processing platform having a operating system and processes said information on said storage device according to said program instructions and wherein said program instructions is designed to run on said operating system.

19. The system of claim 18, further comprising means for allowing a user to select said information on said storage device to be processed by said proxy server computer and to specify a type of processing for said information on said storage device, wherein said requests generated by said client computer for processing said information on said storage device also include data identifying said information on said storage device and said type of processing specified by said user.
