Abstract

The invention provides a method, system, and program product for caching application data in a browser cache. In one embodiment, a method according to the invention includes: providing to a web browser a uniform resource locator (URL) directed to application data; making a hypertext transfer protocol (HTTP) request using the URL; caching in the web browser cache the application data; determining whether the application data has changed since caching; in the case that the application data has changed since caching, providing to the web browser an updated URL directed to changed application data; and in the case that the application data has not changed since caching, using the cached application data.

Claims

1. A method for caching application data in a web browser cache, the method comprising:

providing to a web browser a uniform resource locator (URL) directed to application data;

making a hypertext transfer protocol (HTTP) request using the URL; and

caching in the web browser cache the application data.

2. The method of claim 1, wherein the URL is provided by a server.

3. The method of claim 1, further comprising:

determining whether the application data has changed since caching; and

in the case that the application data has changed since caching, providing to the web browser an updated URL directed to changed application data.

4. The method of claim 3, wherein determining and providing are performed by a server.

5. The method of claim 3, wherein determining includes comparing a timestamp of the URL to a timestamp of the application data.

6. The method of claim 3, further comprising:

making an HTTP request using the updated URL; and

caching in the web browser cache the changed application data.

7. The method of claim 3, further comprising:

in the case that the application data has not changed since caching, using the cached application data.

8. The method of claim 1, wherein providing includes writing the URL using a JAVA server page (JSP) tag.

9. A system for caching application data in a web browser cache, the system comprising:

a system for providing to a web browser a uniform resource locator (URL) directed to application data;

a system for making a hypertext transfer protocol (HTTP) request using the URL; and

a system for caching in the web browser cache the application data.

10. The system of claim 9, further comprising:

a system for determining whether the application data has changed since caching; and

a system for providing to the web browser an updated URL directed to changed application data.

11. The system of claim 10, wherein the system for determining includes a system for comparing a timestamp of the URL to a timestamp of the application data.

12. The system of claim 10, further comprising:

a system for making an HTTP request using the updated URL; and

a system for caching in the web browser cache the changed application data.

13. The system of claim 10, further comprising:

a system for using the cached application data.

14. The system of claim 9, wherein the system for providing includes a system for writing the URL using a JAVA server page (JSP) tag.

15. A program product stored on a computer-readable medium, which when executed, caches application data in a web browser cache, the program product comprising:

program code for providing to a web browser a uniform resource locator (URL) directed to application data;

program code for making a hypertext transfer protocol (HTTP) request using the URL; and

program code for caching in the web browser cache the application data.

16. The program product of claim 15, further comprising:

program code for determining whether the application data has changed since caching; and

program code for providing to the web browser an updated URL directed to changed application data.

17. The program product of claim 16, wherein the program code for determining includes program code for comparing a timestamp of the URL to a timestamp of the application data.

18. The program product of claim 16, further comprising:

program code for making an HTTP request using the updated URL; and

program code for caching in the web browser cache the changed application data.

19. A method for deploying an application for caching application data in a browser cache, comprising:

providing a computer infrastructure being operable to;

provide to a web browser a uniform resource locator (URL) directed to application data;

make a hypertext transfer protocol (HTTP) request using the URL; and

cache in the web browser cache the application data.

20. The method of claim 19, further comprising:

providing a computer infrastructure being operable to;

determine whether the application data has changed since caching; and

in the case that the application data has changed since caching, provide to the web browser an updated URL directed to changed application data.
