The standard solution to these problems is to use a caching proxy. However, a single caching proxy is a bottleneck: there is a limit to the number of clients that can use the same cache, and thereby the effectiveness of the cache is limited. Also, a caching proxy is a single point of failure. We address these problems by creating a protocol that allows multiple caching proxies to cooperate and share their caches, thus increasing robustness and scalability. This scalability, in turn, gives each client an effectively larger cache with a higher hit rate. This paper describes a prototype implementation of this protocol that uses IP multicast to communicate between the servers.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Due to its exponential growth, the World Wide Web is increasingly experiencing several problems, such as hot spots, increased network bandwidth usage, and excessive document retrieval latency.
