System and method for maintaining consistent independent server-side state among collaborating servers
First Claim
1. A method of replicating server-side state information among a plurality of collaborating servers connected to a network, the method comprising:
- determining at a subscriber server from information stored on a client computer whether an event has been performed on a publisher server at the request of the client computer, which event implicates a need for state change on the subscriber server; and
if such an event has been performed, replicating state effects of the event into state on the subscriber server.

Abstract
A system and method are provided for maintaining consistent server-side state across a pool of collaborating servers with independent state repositories. When a client performs an event on a collaborating server which affects such state on the server, it publishes notification of the event into a queue maintained in client-side state which is shared by all of the collaborating servers in the pool. As the client makes requests to servers within the pool, the queue is thus included in each request. When a collaborating server needs to access its server-side state in question, it first discerns events new to it from the queue and replicates their effects into such server-side state. As a result, the effects of events upon server-side state are replicated asynchronously across the servers in the pool, as the client navigates among them.
