Abstract

A web application residing in a client device generates a user interface containing data objects hosted on a remote server. The web application contains a web app cache storing the data objects rendered in a web page. As additional data objects are needed, the web application searches for them first in the web app cache, then a browser cache, before utilizing a web browser to retrieve the data objects from the remote server.

Claims

1. A computer-implemented method, comprising:

storing, at a client device, a plurality of data objects in a browser cache, each data object associated with data residing on a remote server that is accessible through a browser;

searching for the data object in the browser cache;

using the data object stored in the browser cache to generate a user interface; and

rendering the user interface for display.

2. The computer-implemented method of claim 1, further comprising:

generating a URL including a version identifier; and

using the URL to search for the data object in the browser cache.

3. The computer-implemented method of claim 1, further comprising:

obtaining a current copy of the data object from the remote server; and

determining that the data object in the browser cache matches the current copy of the data object from the remote server.

4. The computer-implemented method of claim 1, further comprising:

obtaining a current copy of the data object from the remote server;

determining that the data object in the browser cache differs from the current copy of the data object from the remote server; and

rendering the current copy of the data object.

5. The computer-implemented method of claim 1, further comprising:

prior to storing the data object in a browser cache, receiving the data object from the file hosting server with a cacheable indicator that is set to indicate that the data object is current.

6. The computer-implemented method of claim 5, wherein the cacheable indicator is set when a request for the data object specifies a version that matches a version of the data object stored on the remote server.

7. The computer-implemented method of claim 1, further comprising:

storing the data object, in a web app cache;

prior to searching for the data object in the browser cache, searching for the data object in the web app cache; and

prior to searching for the data object in the browser cache, determining that the data object is not found in the web app cache.

8. The computer-implemented method of claim 7, wherein the remote server is a file hosting server.

14. The computer-readable storage medium of claim 1, storing thereon processor-executable instructions, further comprising:

instructions, that when executed on a processor, obtains a current copy of the data object from the remote server, when a transaction identifier used in a request for the data object does not match a transaction identifier returned in a response with the data object.

9. A computer-readable storage medium storing thereon processor-executable instructions, comprising:

instructions, that when executed on a processor, searches for data object in a web app cache, the web app cache storing data object pertaining to a user interface displayed by a browser, the data object stored on a remote server;

instructions, that when executed on a processor, searches for the data object in a browser cache when no match is found for the data object in the web app cache; and

instructions, that when executed on a processor, requests the data object from the remote server when no match is found for the data object in the browser cache.

10. The computer-readable storage medium of claim 9, storing thereon processor-executable instructions, further comprising:

instructions, that when executed on a processor, store the data object in the browser cache when the data object matches a version stored in the remote server.

11. The computer-readable storage medium of claim 9, storing thereon processor-executable instructions, further comprising:

instructions, that when executed on a processor, renders the data object in a web page when the data object is found in a browser cache; and

instructions, that when executed on a processor, obtains a current copy of the data object from the remote server.

12. The computer-readable storage medium of claim 11, storing thereon processor-executable instructions, further comprising:

instructions, that when executed on a processor, renders the current copy of the data object.

13. The computer-readable storage medium of claim 9, storing thereon processor-executable instructions, further comprising:

instructions, that when executed on a processor, utilizes a URL having a version identifier to obtain the data object.

15. A computer-implemented system, comprising:

a remote server storing a plurality of data objects; and

a client device having a browser for rendering a user interface having one or more data objects obtained from the remote server,

the browser having a web application and a browser cache,

the web application having instructions that when executed on a processor accesses the data object from the remote server to generate a user interface using a data object, the remote server remotely accessible by the browser,

the browser cache having a plurality of URLs, each URL used to obtain data object from the remote server.

16. The computer-implemented system of claim 15, wherein each URL includes a version identifier associated with a data object.

17. The computer-implemented system of claim 16, the web application, having instructions that when executed on a processor, generates a request to obtain data object including the URL.

18. The computer-implemented system of claim 17, the web application, having instructions that when executed on a processor, receives a response having the data object and a cacheable content identifier, the cacheable content identifier set if the version identifier sent in a request and the version identifier associated with the remote server match.

19. The computer-implemented system of claim 15, the web application, having instructions that when executed on a processor, searches for data object in the browser cache.

20. The computer-implemented system of claim 19, the web application, having instructions that when executed on a processor, obtains a current copy of the data object from the remote server and renders the current copy of the data object.
