A method and apparatus for providing application-layer information persistence and exchange. An information space is constructed to span a group of one or more serverss (102a-102f). A coordination entity manages storage of tuples within the information space. Applications access tuples by consulting a local cache (204) of known tuple locations. A local server (102) is queried to determine a correct tuple location, generate a re-route, exception and directed to the known location. This cause the accessing application to query the coordination entity, retry the access, and update the local cache (204).
