Abstract

The present invention relates to systems, apparatus, and methods of accelerating web transactions. One embodiment includes method of optimizing web browser page loads in a network communication system where a hint request is transmitted from a user computer to an optimization server based on a user browsing indicator associated with a root HTTP request, receiving, at the user computer, a set of hints associated with the root object in response to the transmission of the hint request, and modifying, using the user computer, a page load process involving the root object using the set of hints. Additional embodiments involve analyzing web page transactions using a browser plug in module to identify feedback information and prefetch web objects in conjunction with a smart manifest file or browsing hint information associated with the web page transaction.

Claims

1. A method of optimizing web browser page loads in a network communication system comprising:

transmitting, from a user computer to an optimization server, a hint request based on a user browsing indicator associated with a root hypertext transport protocol (HTTP) request for a root object;

receiving, at the user computer from the optimization server, a set of hints associated with the root object in response to the transmission of the hint request;

transmitting, from the user computer to a content server, the root HTTP request for the root object;

transmitting, from the user computer to the content server, at least one child HTTP request based on at least one of the set of hints;

wherein the optimization server is different than the content server;

wherein the method further comprises prefetching a plurality of child objects for the root HTTP request based on the set of hints, wherein the set of hints comprises a list of child objects for the root HTTP request;

wherein the set of hints further comprises a list of interdependencies among the plurality of child objects; and

wherein prefetching the plurality of child objects for the root HTTP request comprises requesting a first subset of the plurality of child objects and then requesting a second subset of the plurality of child objects that is dependent upon the first subset of the plurality of child objects.

2. The method of claim 1 further comprising:

prior to receiving the set of hints at the user computer from the optimization server, observing, using a first computer, a web transaction including the root HTTP request;

creating, by the first computer, a set of web transaction information based on the observing of the web transaction;

receiving, at a database computing device from the first computer, the set of web transaction information; and

updating, using the set of web transaction information at the database computing device, the set of hints associated with efficient downloading of a web browser page.

3. The method of claim 2 wherein the set of web transaction information comprises the root HTTP request, a list of child HTTP requests, and a list of child HTTP responses.

4. The method of claim 3 wherein the set of web transaction information further comprises request and response timings for child HTTP requests and responses identified during observation of the web transaction.

5. The method of claim 4 wherein updating the hint information comprises:

parsing the request and response timings to identify a child object download order identifying the second subset of the plurality of child objects that is dependent upon the first subset of the plurality of child objects; and

including child object download order information in the set of hints.

6. The method of claim 3 wherein the set of web transaction information comprises:

a set of formula used to create at least one child URL; and

a list of input sources for the set of formula.

7. The method of claim 6 wherein the input sources are specified in JavaScript source code and JavaScript functions.

8. The method of claim 7 wherein the one or more child objects comprises at least two child objects from different hosts.

9. The method of claim 3 wherein the set of web transaction information comprises a list of interdependency relationships between child objects.

10. The method of claim 2 wherein the first computer is a proxy server and the database computing device is the proxy server.

11. The method of claim 2 wherein the first computer is a user computer operating a web browser that initiates the web transaction.

12. The method of claim 2 wherein the set of hints comprises a list of one or more child objects for the root HTTP request of the web transaction.

13. The method of claim 2 wherein the method further comprises:

communicating the set of hints to a web browser; and

using the set of hints with a browser module to render a web page associated with the web transaction.

14. The method of claim 2 wherein the set of hints comprises a manifest file that includes information associated with efficient downloading of a subsequent web page associated with the root HTTP request.

15. The method of claim 1 wherein the set of hints further comprises a file size, a last mod time, and a checksum for at least one child object of the plurality of child objects.

16. A method of optimizing web browser page loads in a network communication system comprising:

transmitting, from a user computer to an optimization server, a hint request based on a user browsing indicator associated with a root hypertext transport protocol (HTTP) request for a root object;

receiving, at the user computer from the optimization server, a set of hints associated with the root object in response to the transmission of the hint request;

transmitting, from the user computer to a content server, the root HTTP request for the root object;

transmitting, from the user computer to the content server, at least one child HTTP request based on at least one of the set of hints;

wherein the optimization server is different than the content server;

wherein the method further comprises prefetching a plurality of child objects for the root HTTP request based on the set of hints, wherein the set of hints comprises a list of child objects for the root HTTP request;

wherein the set of hints further comprises a list of generated child uniform resource locators (URLs) and a set of information required for the list of generated child URLs; and

wherein prefetching the plurality of child objects comprises using the set of information to create at least one generated child URL and an HTTP request for the at least one generated child URL.

17. The method of claim 16 wherein set of information comprises at least one formula and instructions for retrieving any information required by the at least one formula.

18. The method of claim 16 wherein the transmitting of the root HTTP request occurs prior to the receiving of the set of hints.

19. The method of claim 16 wherein the method further comprises:

communicating the set of hints to a web browser of the user computer; and

using the set of hints with a browser module to render a web page associated with the web transaction.

20. A method of optimizing web browser page loads in a network communication system comprising:

transmitting, from a user computer to an optimization server, a hint request based on a user browsing indicator associated with a root hypertext transport protocol (HTTP) request for a root object;

receiving, at the user computer from the optimization server, a set of hints associated with the root object in response to the transmission of the hint request;

transmitting, from the user computer to a content server, the root HTTP request for the root object;

transmitting, from the user computer to the content server, at least one child HTTP request associated with at least one child object based on at least one of the set of hints;

wherein the optimization server is different than the content server; and

wherein transmitting the at least one child HTTP request based on the at least one of the set of hints comprises transmitting the at least one child HTTP request to an alternative URL when the set of hints further comprises the alternative URL for the at least one child object, and wherein the alternative URL is for a URL at a dynamic content delivery network (CDN).

21. The method of claim 20 wherein the transmitting of the root HTTP request occurs after the receiving of the set of hints.

22. The method of claim 20 wherein the method further comprises:

communicating the set of hints to a web browser; and

using the set of hints with a browser module to render a web page associated with the web transaction.
