Abstract
A server complex including at least one hit server with item cache, used to process read and write operations relating to cached items from clients, and at least one miss server, serving as a link to other servers (e.g., web servers, file system servers, and databases) for receiving requests relayed from the hit server(s) which relate to non-cached items and for responding to same. The hit server is a general-purpose, generic, component, which is independent of concrete applications and is basically responsible for the performance; while a miss server is a highly-customizable component, which is responsible for flexibility, and is application specific. The inventive architecture provides improved performance whereby a server complex achieves exceptionally high throughput rates for local services (i.e., services using items in the local item cache); flexibility, whereby a server complex can support the enforcement of a variety of application-specific policies for item management, authentication, and item consistency; security, whereby a server complex can enable the verification of the source, integrity, and freshness of communications over untrusted links; and, scalability, whereby…
