Abstract

A system including a user agent configured to transmit request data to a content server, wherein the request data corresponds to a request for a web page; and an optimization server configured to receive a first response data corresponding to the request data from a content server, identify response object data within the first response data, query the content server for second response data that is associated with the identified response object data, and transmit optimized data to the user agent, wherein the contents of the optimized data can include the first response data and the second response data.

Claims

1. A method comprising:

transmitting request data to a content server, wherein the request data correlates to requesting a web page;

receiving first response data from the content server, wherein the first response data corresponds to the request data;

identifying response object data within the first response data;

querying the content server for second response data that is associated with the identified response object data; and

providing optimized data to a user agent, wherein the optimized data can include the first response data and the second response data.

2. The method of claim 1, further comprising identifying request object data within the request data.

3. The method of claim 2, further comprising determining whether the response object data matches the request object data.

4. The method of claim 3, further comprising indicating that the response object data is to be downloaded if the response object data does not match the request object data.

5. The method of claim 3, further comprising determining whether the request object data is fresh or stale if the response object data matches the request object data.

6. The method of claim 5, further comprising indicating that the response object data can be deleted if the request object data is fresh.

7. The method of claim 5, further comprising determining whether the content server verified that the request object data was fresh or stale if the request object data is stale.

8. The method of claim 7, further comprising indicating that the response object data is to be downloaded if the content server verifies that the matching request object data is stale.

9. The method of claim 7, further comprising indicating that the response object data is to be downloaded if the content server verifies that the matching request object data is fresh.

10. The method of claim 7, further comprising indicating that the response object data is not to be downloaded if the content server verifies that the matching request object data is fresh.

11. The method of claim 10, further comprising updating a freshness cache so that the client device can notify the user agent that a subsequent request object data that is marked as stale is fresh.

12. The method of claim 10, further comprising updating content data from stale to fresh at a data cache of the user agent.

13. The method of claim 1, further comprising determining whether the response object data is to be downloaded to a user agent.

14. The method of claim 13, wherein the optimized data includes the second response data if the response object data is to be downloaded to the user agent.

15. The method of claim 13, wherein the optimized data does not include the second response data if the response object data is not to be downloaded to the user agent.

16. A method comprising:

receiving first response data from a content server, wherein the first response data corresponds to a request for a web page;

identifying response object data within the first response data;

querying the content server for second response data that is associated with the identified response object data; and

transmitting optimized data that includes the first response data and the second response data.

17. The method of claim 16, further comprising determining whether a request data includes a request object list, wherein the request data corresponds to the first response data.

18. The method of claim 17, further comprising providing the request object list identifying request object data within the request data if the request data includes a request object list.

19. The method of claim 18, further comprising determining whether the response object data matches the request object data.

20. The method of claim 19, further comprising indicating that the response object data is to be downloaded if the response object data does not match the request object data.

21. The method of claim 19, further comprising determining whether the request object data is fresh or stale if the response object data matches the request object data.

22. The method of claim 21, further comprising indicating that the response object data can be deleted if the request object data is fresh.

23. The method of claim 21, further comprising verifying with the content server that the request object data was fresh or stale if the request object data is stale.

24. The method of claim 23, further comprising indicating that the response object data is to be downloaded if the request object data has been verified to be stale.

25. The method of claim 23, further comprising indicating that the response object data is to be downloaded if the request object data has been verified to be fresh.

26. The method of claim 23, further comprising indicating that the response object data is not to be downloaded if the request object data has been verified to be fresh.

27. The method of claim 16, further comprising determining whether the response object data is to be downloaded to a user agent.

28. The method of claim 27, wherein the optimized data includes the second response data if the response object data is to be downloaded to the user agent.

29. The method of claim 27, wherein the optimized data does not include the second response data if the response object data is not to be downloaded to the user agent.

30. A method comprising

transmitting request data to a content server, wherein the request data correlates to a web page and the request data includes an embedded request object data;

and

receiving optimized data that includes first response data and second response data, wherein the first response data is provided by the content server in response to the request data and the second response data corresponds to the embedded request object data.

31. The method of claim 30, further comprising identifying the embedded request object data of the request data by generating a request object list that provides the identification.

32. The method of claim 31, further comprising determining whether the embedded request object data is fresh.

33. The method of claim 32, further comprising updating the request object list by marking the embedded request object data as being fresh if the embedded request object data is fresh.

34. The method of claim 32, further comprising updating the request object list by marking the embedded request object data as being stale if the embedded request object data is not fresh.

35. The method of claim 32, further comprising retrieving any existing cookie data corresponding to the embedded request object data as being stale if the embedded request object data is not fresh.

36. The method of claim 35, further comprising updating the request object list by including the any existing cookie data.

37. The method of claim 30, wherein the second response data is based on a comparison between the embedded request object data and response object data of the first response data.
