Abstract

A system, a computer readable storage medium including instructions, and a computer-implemented method of pre-fetching in a network. A request is received from a user device for a first web page, the first web page being upstream of other web pages in a page flow. The first web page is transmitted to the user device. At least one web page that is downstream of the first web page in the page flow is transmitted to the user device, the at least one web page being transmitted without receiving a request for the at least one web page.

Claims

1. A computer-implemented method of pre-fetching in a network, comprising:

receiving a request from a user device for a first web page, the first web page being upstream of other web pages in a page flow;

transmitting the first web page to the user device; and

transmitting at least one web page that is downstream of the first web page in the page flow to the user device, the at least one web page being transmitted without receiving a request for the at least one web page.

2. The computer-implemented method of claim 1, wherein transmitting the at least one web page that is downstream of the first web page in the page flow to the user device includes:

determining viewing frequencies of web pages that are downstream of the first web page; and

transmitting at least one of the most frequently viewed web pages that are downstream of the first web page to the user device.

3. The computer-implemented method of claim 1, wherein transmitting the at least one web page that is downstream of the first web page in the page flow to the user device includes:

analyzing code included in the first web page to identify a further web page that is downstream of the first web page in the page flow; and

transmitting the further web page that is downstream of the first web page to the user device.

4. The computer-implemented method of claim 1, wherein transmitting the at least one web page that is downstream of the first web page in the page flow to the user device includes:

identifying a further web page that is downstream of the first web page in the page flow and that is likely to be requested; and

transmitting the further web page that is downstream of the first web page to the user device.

5. The computer-implemented method of claim 1, wherein transmitting the at least one web page that is downstream of the first web page in the page flow to the user device includes transmitting a portion of the at least one web page that is downstream of the first web page in the page flow to the user device.

8. The computer-implemented method of claim 1, wherein prior to transmitting the at least one web page that is downstream of the first web page in the page flow to the user device, the method includes determining the page flow for a plurality of web pages that includes the first web page and at least one downstream web page.

9. The computer-implemented method of claim 1, wherein the at least one web page that is downstream of the first web page in the page flow is transmitted to the user device only after the first web page has been completely transmitted to the user device.

10. The computer-implemented method of claim 1, wherein prior to transmitting the first web page, the method further comprises embedding pre-fetch logic into the first web page, the pre-fetch logic being executable by the user device to cause the user device to pre-fetch the at least one web page that is downstream of the first web page in the page flow.

11. The computer-implemented method of claim 1, wherein prior to transmitting the at least one web page that is downstream of the first web page in the page flow to the user device, the method further comprises receiving a request from the user device to pre-fetch the at least one web page that is downstream of the first web page in the page flow.

6. The computer-implemented method of claim 6, wherein the portion of the at least one web page that is downstream of the first web page in the page flow includes static objects for the at least one web page that is downstream of the first web page.

7. The computer-implemented method of claim 6, further comprising:

receiving a request from the user device for the at least one web page that is downstream of the first web page in the page flow; and

transmitting a remaining portion of the at least one web page that is downstream of the first web page in the page flow to the user device.

12. A system, comprising:

a receiving module configured to receive a request from a user device for a first web page, the first web page being upstream of other web pages in a page flow; and

a transmitting module, implemented using one or more processors, configured to;

transmit the first web page to the user device; and

transmit at least one web page that is downstream of the first web page in the page flow to the user device, the at least one web page being transmitted without receiving a request for the at least one web page.

13. The system of claim 12, wherein when transmitting the at lest one web page that is downstream of the first web page in the page flow to the user device, the transmitting module is configured to:

determine viewing frequencies of web pages that are downstream of the first web page; and

transmit at least one of the most frequently viewed web pages that are downstream of the first web page to the user device.

14. The system of claim 12, wherein when transmitting the at least one web page that is downstream of the first web page in the page flow to the user device, the transmitting module is configured to:

analyze code included in the first web page to identify a further web page that is downstream of the first web page in the page flow; and

transmit the further web page that is downstream of the first web page to the user device.

15. The system of claim 12, wherein when transmitting the at least one web page that is downstream of the first web page in the page flow to the user device, the transmitting module is configured to:

identify a further web page that is downstream of the first web page in the page flow and that is likely to be requested; and

transmit the further web page that is downstream of the first web page to the user device.

16. The system of claim 12, wherein when transmitting the at least one web page that is downstream of the first web page in the page flow to the user device, the transmitting module is configured to transmit a portion of the at least one web page that is downstream of the first web page in the page flow to the user device.

17. The system of claim 16, wherein the portion of the at least one web page that is downstream of the first web page in the page flow includes static objects for the at least one web page that is downstream of the first web page.

18. The system of claim 16,

wherein the receiving module is configured to receive a request from the user device for the at least one web page that is downstream of the first web page in the page flow;

and

wherein the transmitting module is configured to transmit a remaining portion of the at least one web page that is downstream of the first web page in the page flow to the user device.

19. The system of claim 12, further comprising:

a processor;

wherein prior to transmitting the at least one web page that is downstream of the first web page in the page flow to the user device, the processor is configured to determine the page flow for a plurality of web pages that includes the first web page and at least one downstream web page.

20. The system of claim 12, wherein the at least one web page that is downstream of the first web page in the page flow is transmitted to the user device only after the first web page has been completely transmitted to the user device.

21. The system of claim 12, further comprising:

a processor,

wherein prior to transmitting the first web page, the processor is configured to embed pre-fetch logic into the first web page, the pre-fetch logic being executable by the user device to cause the user device to pre-fetch the at least one web page that is downstream of the first web page in the page flow.

22. The system of claim 12, wherein prior to transmitting the at least one web page that is downstream of the first web page in the page flow to the user device, the receiving modules is configured to receive a request from the user device to pre-fetch the at least one web page that is downstream of the first web page in the page flow.

23. A computer readable storage medium storing at least one program configured for execution by a computer, the at least one program comprising instructions to:
