Disconnected operation, in which a client accesses a service without relying on network connectivity, is crucial for improving availability, supporting mobility, and providing responsive performance. Because many web services are not cachable, disconnected access to web services may require mobile service code to execute in client caches. Furthermore as web workloads access large amounts of data, disconnected access must require prefetching data that will later be used on demand. Unfortunately, this can significantly increase the total amount of data fetched by a service. In this thesis we present an argument thaat aggressive prefetching is feasible. A study of the web workload characteristics at typical clients suggests a need for a flexible, automated resource management system to prevent denial of service attacks by these potentially unreliable mobile service codes that prefetch at the clients. We therefore present and evaluate a Popularity based resource management policy for such an environment.
