A system for dynamically changing session behavior based on user and/or group classification in response to server demand. The system operates to dynamically alter current session behavior experienced by individual users and/or groups of users in response to monitored server demand. An intelligence server provides application servers with actions to be taken to dynamically change current user sessions, in response to current server demand, for example based on rules known by a rules engine within the intelligence server. A ranking system within the intelligence server takes its input from a monitoring system also in the intelligence server, and dynamically keeps track of individual user's relative ranks against other users that are actively being monitored.
