Abstract
A system and method are provided for replicating state among collaborating World Wide Web servers connected to a computer network. When a collaborating Web server needs to access state information, the collaborating Web server first determines whether the state information has been modified since the last time the collaborating Web server accessed the state information. If the state information has been modified, the collaborating Web server requests a copy of the state information from the last collaborating Web server to modify the state information. As a result, state information is only replicated among collaborating Web servers on an as-needed basis, greatly reducing the amount of data that needs to be replicated among collaborating Web servers.
