Abstract

Systems, methods and media for sharing session data on a network are disclosed. More particularly, hardware and/or software for sharing user session data between different servers on a network are disclosed. Embodiments include a data processing system for sharing session data on a network, where the network includes an application server and an enterprise server, each providing at least part of an application to a user on the network. In some embodiments, the application server includes a session transport component for recording changes to user session data with the application server and the enterprise server includes a session transport component for requesting updated user session data from the application server. In further embodiments, the enterprise server may establish a user session based on the updated user session data received from the application server.

Claims

1. A data processing system for sharing session data on a network, the system comprising:

an application server, the application server being adapted to provide at least part of an application to a user on the network, the user having an established session on the application server, wherein the user session has associated session data;

a session transport component of the application server, wherein the session transport component of the application server is adapted to record changes to the session data and adapted to communicate with other servers;

an enterprise server in communication with the application server, the enterprise server being adapted to provide at least part of an application to a user on the network; and

a session transport component of the enterprise server in communication with the session transport component of the application server, wherein the session transport component of the enterprise server is adapted to request updated user session data from the application server.

2. The system of claim 1, further comprising an HttpSession component located on the application server for determining which methods will modify the session data.

3. The system of claim 1, further comprising an HttpSession component located on the enterprise server for determining which methods will modify the session data and for determining which methods will require updated session data.

4. The system of claim 1, further comprising a post aspect component of the application server, the post aspect component being adapted to transmit notification of a change in the session data to the session transport component of the application server.

5. The system of claim 1, further comprising a pre aspect component of the enterprise server, the pre aspect component being adapted to request updated session data from the session transport component of the enterprise server.

6. The system of claim 1, further comprising a post aspect component of the enterprise server, the post aspect component being adapted to transmit notification of a change in the session data to the session transport component of the enterprise server.

7. The system of claim 1, wherein the session transport component of the enterprise server is further adapted to transmit modifications to the session data made at the enterprise server to the application server.

8. The system of claim 1, wherein the enterprise server is further adapted to establish a user session based on the updated user session data from the application server.

9. The system of claim 1, wherein the session data comprises HttpSession data.

10. The system of claim 1, wherein the network is the Internet.

11. The system of claim 1, wherein the application server is an edge application server.

12. The system of claim 1, wherein the application server is an Internet Information Server.

13. The system of claim 1, wherein the enterprise server is a J2EE application server.

14. A method for sharing session data between servers, the method comprising:

at an enterprise server, determining that updated session data will be needed by a method of the enterprise server and requesting new session data from an application server;

at the application server, receiving a request for updated session data, the request being subsequent to a previous request, the updated session data comprising any changes to the session data since the previous request;

transmitting the updated session data from the application server to the enterprise server; and

creating a local session at the enterprise server based on the updated session data.

15. The method of claim 14, further comprising at the enterprise server, identifying a network address for the application server.

16. The method of claim 14, further comprising forcing session data retrieval from the application server.

17. The method of claim 14, further comprising:

determining that session data has been modified at the enterprise server; and

transmitting an indication of the modified session data from the enterprise server to the application server.

18. The method of claim 14, further comprising at the application server, determining whether the session data was modified since the previous request.

19. The method of claim 14, further comprising at the application server, saving an indication of the request for updated session data.

20. The method of claim 14, further comprising at the application server, receiving new session data from the application server.

21. The method of claim 14, further comprising before receiving a request for updated session data at the application server, saving an indication of the session data being modified.

22. The method of claim 14, wherein the session data comprises HttpSession data.

23. The method of claim 14, wherein the received updated session data comprises an indication that the session data has not changed, and wherein further creating a new local session based on the received updated session data comprises creating a new local session based on a user request.

24. A machine-accessible medium containing instructions effective, when executing in a data processing system, to cause said data processing system to perform operations comprising:

at an enterprise server, determining that updated session data will be needed by a method of the enterprise server and requesting new session data from an application server;

at the application server, receiving a request for updated session data, the request being subsequent to a previous request, the updated session data comprising any changes to the session data since the previous request;

transmitting the updated session data from the application server to the enterprise server; and

creating a local session at the enterprise server based on the updated session data.

25. The machine-accessible medium of claim 24, further comprising at the enterprise server, identifying a network address for the application server.

26. The machine-accessible medium of claim 24, further comprising forcing session data retrieval from the application server.

27. The machine-accessible medium of claim 24, further comprising:

determining that session data has been modified at the enterprise server; and

transmitting an indication of the modified session data from the enterprise server to the application server.

28. The machine-accessible medium of claim 24, further comprising at the application server, determining whether the session data was modified since the previous request.

29. The machine-accessible medium of claim 24, further comprising at the application server, saving an indication of the request for updated session data.

30. The machine-accessible medium of claim 24, further comprising at the application server, receiving new session data from the application server.
