Abstract

Enhanced client-server communication in a cached communication environment is described. A server computer executes a server application. The server application requests a server communication application to generate a server object. The server object is independent from a client object that is modified to communicate client data. The server object is associated with a server object identifier. The server application receives a copy of the client object from the server communication application. The copy of the client object is associated with a client object identifier. The server application determines whether the server object identifier has an expected relationship with the client object identifier. The server application applies a disposition rule to data referenced in the copy of the client object if the server object identifier has the expected relationship with the client object identifier.

Claims

1. A system for enhanced client-server communication in a cached communication environment, the system comprising:

one or more processors; and

a non-transitory computer-readable medium storing a plurality of instructions, which when executed cause the one or more processors to;

request a server communication application to generate a server object as a read and write object, which communicates server data from a server computer to a client computer in response the server object being modified, generate a server object identifier associated with the server object on the server computer, and generate a copy on the server computer of a client object in response to a client communication application generating the client object on the client computer, the server object being independent from the client object stored on the client computer, the client object being a read and write object, which communicates client data from the client computer to the server computer in response the client object being modified;

receive a copy of the modified client object stored on the client computer from the server communication application, the copy of the modified client object being a read only object wherein the copy of the modified client object is associated with a client object identifier;

use the received copy of the modified client object to synchronize the copy of the client object on the server computer, independently from modifying the server object;

determine whether the server object identifier has an expected relationship to the client object identifier;

apply a disposition rule, independent of data referenced in the server object, to data referenced in the copy of the modified client object received before the determination whether the server object identifier has the expected relationship to the client object identifier, the application of the disposition rule being in response to a determination that the server object identifier has the expected relationship to the client object identifier; and

postpone application of the disposition rule to data referenced in the copy of the client object until the server object identifier has the expected relationship to the client object identifier.

2. The system of claim 1, wherein the server object identifier is at least one of metadata associated with the server object and an attribute associated with the server object.

3. The system of claim 1, wherein the plurality of instructions, when executed will further cause the one or more processors to modify the server object to generate a copy of the server object.

4. The system of claim 1, wherein the plurality of instructions, when executed will further cause the one or more processors to modify the server object identifier by one of increasing a value of the server object identifier and decreasing the value of the server object identifier.

5. The system of claim 1, wherein the plurality of instructions lacks permission to modify the copy of the client object.

6. The system of claim 1, further comprising a processor-based client application, which when executed will cause the one or more processors to:

request the client communication application to generate the client object;

receive a copy of the server object from the client communication application in response the server object being modified;

determine whether the client object identifier has another expected relationship to the server object identifier and

apply another disposition rule to data referenced in the copy of the server object in response to a determination that the client object identifier has the other expected relationship to the server object identifier.

7. The system of claim 6, wherein the client object identifier is at least one of metadata associated with the client object and an attribute associated with the client object.

8. The system of claim 6, wherein the processor-based client application, when executed will further cause the one or more processors to modify the client object to generate the copy of the modified client object.

9. The system of claim 6, wherein the processor-based client application, when executed will further cause the one or more processors to modify the client object identifier by one of increasing a value of the client object identifier and decreasing the value of the client object identifier.

10. The system of claim 6, wherein the processor-based client application lacks permission to modify the copy of the server object.

11. A computer-implemented method for enhanced client-server communication in a cached communication environment, the method comprising:

requesting a server communication application to generate a server object as a read and write object, which communicates server data from a server computer to a client computer in response the server object being modified, generate a server object identifier associated with the server object on the server computer, and generate a copy on the server computer of a client object in response to a client communication application generating the client object on the client computer, the server object being independent from the client object stored on the client computer, the client object being a read and write object, which communicates client data from the client computer to the server computer in response the client object being modified;

receiving a copy of the modified client object stored on the client computer from the server communication application, the copy of the modified client object being a read only object wherein the copy of the modified client object is associated with a client object identifier;

using the received copy of the modified client object to synchronize the copy of the client object on the server computer, independently from modifying the server object;

determining whether the server object identifier has an expected relationship to the client object identifier;

applying a disposition rule, independent of data referenced in the server object, to data referenced in the copy of the modified client object received before the determination whether the server object identifier has the expected relationship to the client object identifier, the application of the disposition rule being in response to a determination that the server object identifier has the expected relationship to the client object identifier; and

postponing application of the disposition rule to data referenced in the copy of the client object until the server object identifier has the expected relationship to the client object identifier.

12. The method of claim 11 further comprising modifying the server object to communicate server data.

13. The method of claim 11 further comprising:

requesting the client communication application to generate the client object;

receiving a copy of the server object from the client communication application in response the server object being modified;

determining whether the client object identifier has another expected relationship with the server object identifier; and

applying another disposition rule to data referenced in the copy of the server object in response to a determination that the client object identifier has the another expected relationship with the server object identifier.

14. The method of claim 13 further comprising modifying the client object to communicate client data.

15. A computer program product, comprising a non-transitory computer-readable medium having a computer readable program code embodied therein to be executed by one or more processors, the program code including instructions to:

request a server communication application to generate a server object as a read and write object, which communicates server data from a server computer to a client computer in response the server object being modified, generate a server object identifier associated with the server object on the server computer, and generate a copy on the server computer of a client object in response to a client communication application generating the client object on the client computer, the server object being independent from the client object stored on the client computer, the client object being a read and write object, which communicates client data from the client computer to the server computer in response the client object being modified;

receive a copy of the modified client object stored on the client computer from the server communication application, the copy of the modified client object being a read only object wherein the copy of the modified client object is associated with a client object identifier;

use the received copy of the modified client object to synchronize the copy of the client object on the server computer, independently from modifying the server object;

determine whether the server object identifier has an expected relationship to the client object identifier;

apply a disposition rule, independent of data referenced in the server object, to data referenced in the copy of the modified client object received before the determination whether the server object identifier has the expected relationship to the client object identifier, the application of the disposition rule being in response to a determination that the server object identifier has the expected relationship to the client object identifier; and

postpone application of the disposition rule to data referenced in the copy of the client object until the server object identifier has the expected relationship to the client object identifier.

16. The computer program product of claim 15, the program code including further instructions to modify the server object to communicate server data.

17. The computer program product of claim 15, the program code including further instructions to:

request the client communication application to generate the client object;

receive a copy of the server object from the client communication application in response the server object being modified;

determine whether the client object identifier has another expected relationship with the server object identifier; and

apply another disposition rule to data referenced in the copy of the server object in response to a determination that the client object identifier has the other expected relationship with the server object identifier.

18. The computer program product of claim 17, the program code including further instructions to modify the client object to communicate client data.
