The Active HYpermedia Delivery System (AHYDS) within the NACSIS R&D department is an experimental advanced platform developed for delivering hypermedia documents over distributed and heterogeneous systems. The evolution of the network technology and the requirements of multimedia applications suggest that hypermedia and multimedia delivery systems need to be improved in terms of media caching to guarantee data delivery to a large scale of users and also to reduce information traffic within large scale multimedia information systems. Remote main-memory accesses require combining main memory access in a same LAN. In this article, we address the main memory caching capabilities of the AHYDS platform used in a multi-server/multi-client architecture, to optimize the use of the uniform storage management of the underlying data structure. It provides a high performance support in terms of distributed and heterogeneous hypermedia management. We propose two cache algorithms: the "Temperature Adaptation Cache", and the "States Adaptation Cache" for distributed information systems. Performance evaluations show that our proposal reduces the data access latency and increase the hit ratio of accessing data in main memory in a rate between 10 and 20%. The caching algorithms also eliminate the CPU overhead in a range of 50-95% maintaining a high hit ratio.
