Abstract

Methods and systems for reducing web page load time include obtaining speculative information associated with a uniform resource locator (URL). The method and system also include determining whether to prefetch content of the URL based on the speculative information. The method and system further include providing an instruction to prefetch the URL content when a determination to prefetch results. The method and system also include prerendering the URL content when the instruction to prefetch the URL content is provided.

Claims

1. A method for web content prefetching comprising:

obtaining speculative information associated with a uniform resource locator (URL), wherein the speculative information includes a likelihood that a user will navigate to the URL;

determining, using a computing device, whether to prefetch content of the URL based on the speculative information;

providing an instruction to prefetch the URL content when the determining results in a determination to prefetch; and

prerendering the URL content when the instruction to prefetch the URL content is provided.

2. The method of claim 1, further comprising displaying the prerendered URL content.

3. The method of claim 1, wherein prerendering the URL content includes rendering a web page off-screen.

4. The method of claim 1, wherein the speculative information informs the computing device to prerender a web page.

5. The method of claim 4, wherein the speculative information informs the computing device to use the prerendered web page for a specified period of time.

6. The method of claim 4, further comprising determining an expiration of a specific time period to use the prerendered web page.

7. The method of claim 1, wherein obtaining speculative information includes obtaining the speculative information present in a web page header.

8. The method of claim 1, wherein obtaining speculative information includes obtaining the speculative information present in web page content.

9. The method of claim 1, wherein obtaining speculative information includes obtaining the speculative information present in a link tag associated with the URL.

10. The method of claim 1, wherein obtaining speculative information includes obtaining the speculative information included in a directive associated with the URL.

11. The method of claim 1, wherein obtaining speculative information includes obtaining a probability that a user would navigate to the URL.

12. The method of claim 1, wherein the determining comprises determining, using the computing device as a client, whether to prefetch content of the URL based on the speculative information.

13. A system for web content prefetching comprising:

a speculative information acquirer, implemented with a computing device, configured to obtain speculative information associated with a uniform resource locator (URL), wherein the speculative information includes a likelihood that a user will navigate to the URL;

a speculator configured to

determine whether to prefetch content of the URL based on the speculative information; and

provide an instruction to prefetch the URL content when the determining results in a determination to prefetch; and

a renderer configured to prerender the URL content when the instruction to prefetch the URL content is provided.

14. The system of claim 13, wherein the renderer is configured to prerender the URL content when the instruction to prefetch the URL content is provided.

15. The system of claim 13, wherein the renderer is configured to display the prerendered URL content.

16. The system of claim 13, wherein the renderer is configured to render a web page off-screen.

17. The system of claim 13, wherein the speculative information informs the renderer to prerender a web page.

18. The system of claim 13, wherein the speculative information informs the renderer to use the prerendered web page for a specified period of time.

19. The system of claim 13, wherein the renderer is configured to determine an expiration of a specific time period to use the prerendered web page.

20. A computer program product comprising a computer-usable medium having computer program logic recorded thereon for enabling a processor to prefetch web content, the computer program logic comprising:

first computer readable program code that enables a processor to obtain speculative information associated with a uniform resource locator (URL), wherein the speculative information includes a likelihood that a user will navigate to the URL;

second computer readable program code that enables a processor to determine, using a computing device, whether to prefetch content of the URL based on the speculative information;

third computer readable program code that enables a processor to provide an instruction to prefetch the URL content when the determining results in a determination to prefetch; and

fourth computer readable program code that enables a processor to prerender the URL content when the instruction to prefetch the URL content is provided.

21. The computer program product of claim 20, further comprising fifth computer readable program code that enables a processor to display the prerendered URL content.
