Abstract
A system and associated method for managing resources of a network load balancer. The method begins with registering the network load balancer with the presence server. Next the network load balancer notifies the presence server when an end user requests resources from an application server connected to the network load balancer. The network load balancer then provides the end user access to the application server and subscribes to an information feed pertaining to the end user and supplied by the presence server. After receiving a notification from the presence server that the end user changed their presence information, the network load balancer updates their records pertaining to the end user in a database. Finally, the network load balancer determines whether to continue providing the end user with access to the application server or purge the end user's records from the database.
