A method of determining Internet delays associated with requests from a Web client connectable to a Web server. The method begins at the Web server in response to a first HTTP request. In particular, the Web server serves a response to the first HTTP request and logs a server processing time associated with serving that response. After the response is delivered back to the Web client that initiated the request, an end user response time associated with the first HTTP request is calculated at the Web client. Upon a new HTTP request (typically the next one), the end user response time associated with the first HTTP request is then passed from the Web client to the Web server in a cookie. The Internet delay associated with the first HTTP request is then calculated by subtracting the server processing time from the end user response time.
