IDENTIFYING WEB USERS IN A PROXY SERVER

摘要

A facility for identifying users of client computer systems sending server requests to a recipient computer system is described. For each of a plurality of users, the facility selects one address signifying the identity of the user from among a plurality of addresses at which the recipient computer system can receive server requests from client computer systems. For each user, the facility instructs a client computer program on a client computer system used by the user to direct server requests to servers via the selected address. When a server request is received from a client computer system, the facility determines that any of these are based upon the one of the plurality of the addresses at which the request is received.
