Abstract
A client-server application is provided to clients across a network. Requests from the client are accepted by a reliable proxy and sent to master and standby configurations of the client-server application. Each configuration processes the request to produce master and standby responses respectively. The proxy selects one response based on various criteria including a length being greater than the other response by more than a fixed value. The selected response is returned to the client over the internet. The configuration producing the selected response is thereafter designated as the master configuration. A recovery process may be initiated on the unselected configuration.
