Abstract

The intelligent proxy provides a mechanism for the assured once and once only delivery of messages by tolerating the failure of one or more servers which are front-ended by the proxy. The proxy caters for the messaging scenario where delivering a message from a client to the server has been initiated but not completed and message state exists on either the client, server or both when the server fails. This technology relies on the proxy being able to uniquely identify each client when it connects.
