| Abstract: | This paper proposes the concept of a domain cache, which is dedicated to handling access to a particular domain name, and reports experiments in the Japan Cache Project which operates a public cache server for access to JP (Japan) domain web servers. The goal of this project is to spread information about Japan to North America. This project included some experiments in prefetching information to makes use of less crowded access times, maintaining the coherence between the cache server and primary servers by primary server refresh, and operating a cache replication server, which keeps the primary server information in the cache and functions not as a proxy server but as an HTTP server.The high cache hit ratio obtained suggests that domain caching is an effective cache server operation method. However, we could not perform effective prefetching because of the difficulty in predicting user accesses. Coherence maintaining and cache replication server mechanisms were created. We appeal for cooperation from servers in Japan. |
