Filed:

Sep 8, 1997

Appl. No.:

08/924987

Inventors:

Raymond Morris Bryant - Austin TX
Richard Dale Hoffman - Austin TX
Samuel Kahn - Mountain View CA

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 15173

US Classification:

709224, 370216

Abstract:

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.

International Classification:

US Classification:

709224

Abstract:

A method of logging information in a computer network having a Web client connectable to a Web server. In response to the HTTP request (and as a result of receiving a response to that request), a response time associated with that first HTTP request is calculated. Thereafter, the response time calculated is passed from the Web client on a subsequent HTTP request to that Web server, where the information is logged for later use. In a preferred embodiment, the response time associated with the first HTTP request is passed in a cookie of the second HTTP request.
