Abstract

A method and apparatus for redirecting client-side storage operations to one or more remote storage devices. An HTTP message generated by a web server includes one or more client-side storage operations. Based on defined criteria, the client-side storage operations are replaced with remote storage instructions to generate a modified HTTP message. The modified HTTP message is sent towards the client device. A user agent on the client device receives the HTTP message and executes the remote storage instructions. The storage operations are implemented on the remote storage devices rather than on the client.

Claims

1. A method for modifying an HTTP message, comprising:

receiving an HTTP message addressed to a user agent executing on a client device;

detecting in the HTTP message a client-side storage operation directed to the client device;

translating the client-side storage operation into remote storage instructions based on a defined criteria; and

generating a modified HTTP message wherein the client-side storage operation is replaced with the remote storage instructions.

2. The method of claim 1 wherein the remote storage instructions comprises a remote storage device identifier identifying a remote storage device, and at least one remote storage command implementing the client-side storage operation on the remote storage device.

3. The method of claim 1 wherein the remote storage instructions further comprise:

a plurality of remote storage device identifiers, each of the plurality of remote storage device identifiers identifying a corresponding remote storage device, and for each of the remote storage device identifiers, at least one remote storage command implementing the client-side storage operation on the corresponding remote storage device.

4. The method of claim 1 further comprising sending the modified HTTP message toward the user agent.

5. The method of claim 4 wherein the remote storage instructions further comprises a remote storage proxy identifier identifying a remote storage proxy.

6. The method of claim 5 further comprising receiving, by the remote storage proxy, the remote storage instructions from the user agent.

7. The method of claim 6 further comprising sending, by the remote storage proxy, a remote storage command to a remote storage device.

8. The method of claim 1 wherein the remote storage instructions comprise a reference to a file stored on a device other than the client device, and wherein the file identifies a plurality of remote storage devices, and for each of the plurality of remote storage devices, at least one remote storage command implementing the client-side storage operation on the respective remote storage device.

9. The method of claim 8 wherein the remote storage instructions comprise a digitally signed JavaScript file.

10. The method of claim 1 wherein the defined criteria comprises a current location of the client device.

11. The method of claim 1 wherein the defined criteria comprises a type of service identified in the HTTP message.

12. The method of claim 1 wherein the defined criteria comprises a type of data associated with the client-side storage operation.

13. The method of claim 1 wherein the defined criteria comprises a source of data associated with the client-side storage operation.

14. An apparatus comprising:

a communications interface adapted to communicate with a network;

a redirection module coupled to the communications interface and adapted to;

receive an HTTP message addressed to a user agent executing on a client device;

detect in the HTTP message a client-side storage operation directed to the client device;

translate the client-side storage operation into remote storage instructions based on a defined criteria; and

generate a modified HTTP message wherein the client-side storage operation is replaced with the remote storage instructions.

15. The apparatus of claim 14 wherein the apparatus comprises a network element, and wherein the redirection module is further adapted to send the modified HTTP message toward the client device.

16. The apparatus of claim 14 wherein the apparatus comprises the client device.

17. The apparatus of claim 14 wherein the remote storage instructions comprises a remote storage device identifier identifying a remote storage device, and at least one remote storage command implementing the client-side storage operation on the remote storage device.

18. A computer program product comprising a computer usable medium having a computer readable program code embodied therein, said computer readable program code adapted to be executed to implement a method for modifying an HTTP message, said method comprising:

receiving an HTTP message addressed to a user agent executing on a client device;

detecting, in the HTTP message, a client-side storage operation directed to the client device;

translating the client-side storage operation into remote storage instructions based on a defined criteria; and

generating a modified HTTP message wherein the client-side storage operation is replaced with the remote storage instructions.

19. The computer program product of claim 18 wherein the remote storage instructions comprise a remote storage device identifier identifying a remote storage device, and at least one remote storage command implementing the client-side storage operation on the remote storage device.

20. The computer program product of claim 19 wherein the remote storage instructions further comprise a remote storage proxy identifier identifying a remote storage proxy.

21. The computer program product of claim 18 wherein the defined criteria comprises a current location of the client device.
