A management system can associate the behavior of backend and application systems with a web site visitor's browsing behavior and activity at a web site. In one embodiment, the management system can time order requests and events from server computers communicatively connected to the management system. Each of these requests and events may contain a time stamp and a user identification. Each event for a user identified by the user identification is associated with a request from that user that is the closest in time to the event according to the time ordering. This can allow more relevant personalized content be sent to the user based on the user's most recent views and/or activity on the web site.
