Abstract

A system and method are disclosed for gathering information relating to a loading time experienced by a user of information over a network. A browser agent is sent to a user machine in response to a user request to access a Web page. The browser agent initiates the sending of a user HTTP GET request and the browser agent is operable to log a first time corresponding to the sending of the user HTTP GET request. The browser agent measures a download time interval that is determined according to the difference between the first time and a second time corresponding to the loading of the web page. The browser agent is operative to cause the user machine to send a modified HTTP GET request, wherein the modified HTTP GET request contains a performance parameter indicative of the measured download time interval. Thus, the download time interval experienced by the user is measured and a parameter indicative of the measured download time interval is sent as part of the modified HTTP GET request.

Claims

1. A method of gathering information relating to a loading time experienced by a user of information over a network comprising:

automatically sending a browser agent from a remote information source to a user machine in response to a user request to access a Web page, wherein the browser agent is downloaded to the user machine before the Web page and initiates the sending of a user HTTP GET request from the user machine to the remote information source, wherein the browser agent is operable to log a first time corresponding to the sending of the user HTTP GET request, and wherein the browser agent automatically measures a download time interval, the download time interval being determined according to the difference between the first time corresponding to the sending of the HTTP GET request from the user machine and a second time corresponding to the loading of the Web page on the user machine; and

wherein the browser agent is operative to automatically cause the user machine to send a modified HTTP GET request, wherein the modified HTTP GET request contains a performance parameter indicative of the measured download time interval between the sending of the HTTP GET request from the user machine and the loading of the Web page on the user machine;

whereby the download time interval experienced by the user is measured and a parameter indicative of the measured download time interval is sent as part of the modified HTTP GET request.

2. A method as recited in claim 1 wherein the browser agent is further operative to cause the user to send a user information cookie as part of the HTTP GET request, wherein the user information cookie includes information related to the user.

3. A method as recited in claim 2 wherein the information related to the user includes a geographical coordinate.

4. A method as recited in claim 3 wherein the geographical coordinate is predetermined according to a city indicated by the user.

5. A method as recited in claim 1 further including receiving a plurality of user modified HTML requests from a plurality of users and recording a plurality of performance parameters, the plurality of performance parameters being indicative of a plurality of measured download time intervals determined by each of the plurality of users.

6. A method as recited in claim 5 further including generating a map that indicates the performance experienced by users in different regions.

7. A method as recited in claim 1 wherein the modified HTTP GET request is generated by the browser agent.

8. A method as recited in claim 1 wherein the performance parameter is the difference between the first time and the second time.

9. A method as recited in claim 1 wherein the performance parameter is a qualitative evaluation of performance based on the difference between the first time and the second time.

10. A method as recited in claim 1 wherein the second time corresponds to the completion of the loading of the Web page.

11. A method as recited in claim 10 wherein download time interval is equal to the difference between the first time and the second time.

12. A method as recited in claim 1 wherein the network is the Internet.

13. A system for assembling performance data related to the downloading of information from a computer network comprising:

a Web server configured to automatically send a browser agent to a user in response to a user request, wherein the browser agent is downloaded and configured to initiate the sending of a user HTTP GET request, wherein the browser agent is operable to automatically log a first time corresponding to the sending of the user HTTP GET request, and wherein the browser agent is configured to automatically measure a download time interval, the download time interval being determined according to the difference between the first time corresponding to the sending of the user HTTP GET request and a second time corresponding to the loading of the Web page; and

a relay server configured to receive from the user a modified HTTP GET request, wherein the modified HTTP GET request contains a performance parameter indicative of the measured download time interval;

whereby the download time interval experienced by the user is measured and a parameter indicative of the measured download time interval is received as part of the modified HTTP GET request.

14. A system as recited in claim 13 wherein the relay server is configured to receive from the user as part of the HTTP GET request a user information cookie, wherein the user information cookie includes information related to the user.

15. A system as recited in claim 14, wherein the information related to the user includes a geographical coordinate.

16. A system as recited in claim 15 wherein the geographical coordinate is predetermined according to a city indicated by the user.

17. A system as recited in claim 14 wherein the network in the Internet.

18. A system as recited in claim 13 wherein the relay server is operable to receive a plurality of user modified HTML requests from a plurality of users and record a plurality of performance parameters, the plurality of performance parameters being indicative of a plurality of measured download time intervals determined by each of the plurality of users.

19. A system as recited in claim 13 further including means for generating a map that indicates the performance experienced by users in different regions.

20. A system as recited in claim 13 wherein the performance parameter is the difference between the first time and the second time.

21. A system as recited in claim 13 wherein the performance parameter is a qualitative evaluation of performance based on the difference between the first time and the second time.

22. A system as recited in claim 13 wherein the second time corresponds to the completion of the loading of the Web page.

23. A system as recited in claim 13 wherein the download time interval is equal to the difference between the first time and the second time.

24. A system as recited in claim 13 wherein the Web server and the relay server are implemented on a single physical machine.

25. A system as recited in claim 13 wherein the Web server and the relay server are implemented on different physical machines.

26. A system as recited in claim 13 wherein the network is the Internet.

27. A system for assembling performance data related to the downloading of information from a computer network comprising:

a Web server configured to automatically send a browser agent to a user in response to a user request to access a Web page, wherein the browser agent is downloaded before the Web page and configured to initiate sending a user HTTP GET request, wherein the browser agent is operable to log a first time corresponding to the sending of the user HTTP GET request, and wherein the browser agent is configured to measure a download time interval automatically, the download time interval being determined according to the difference between the first time corresponding to the sending of the user HTTP GET request and a second time corresponding to the loading of the Web page; and

wherein the browser agent is configured to send a modified HTTP GET request, the modified HTTP GET request containing a performance parameter indicative of the measured download time interval;

whereby the download time interval experienced by the user is measured and a parameter indicative of the measured download time interval is sent as part of the modified HTTP GET request.

28. A system as recited in claim 27 wherein the download time interval is included in the header of the modified HTTP GET request.

29. A system as recited in claim 27 wherein the network is the Internet.

30. A method of gathering information regarding a loading time experienced at a target location on a network comprising:
