Modern large-scale distributed information systems need to implement specific techniques in order to favor the efficient processing of document access requests. This paper proposes a delivery system that consistently integrates two types of such techniques based on caching: cooperative caching, which promotes the exchange of documents between caches whenever advantageous, and semantic caching, which uses a monitoring of popular topics in order to take decisions on which documents to cache. It also presents the results of the experimental evaluation of this proposal that has been conducted thanks to a simulator of the complete system; these experiments show the potential of the system for effectively reducing access request processing times.
