  • Method and apparatus for evaluating service to a user over the internet
    Patent number: 6625647
    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.
