Approach for managing state information by a group of servers that services a group of clients
An approach for managing state information by a group of servers that services a group of clients is disclosed. One server is designated as the primary server and is responsible for generating state information to be used by both the servers and the clients. The remaining servers are designated as secondary servers that help to manage the group, but which do not generate the state information.

The Applet Group Controller maintains an association with each applet that maintains the keys and values of any parameters and variables for the applet. In a preferred embodiment, upon the invocation of an event, the association instructs an Action Coordinator to invoke an action. The Action Coordinator obtains and transmits a list of all of the keys and their values to the server. The server invokes the appropriate application logic and transmits the keys and their values (as updated during the execution of the application logic) back to the Action Coordinator. The Action Coordinator then pushes the updated values out to the applets (through their Associations) at which time the browser's display is updated with the new values.
