Scalable Highly Available Web Caching

This paper proposes translucent caching as an alternative to transparent caches Translucent caches use the fact that network routing forwards a request for an object along the best path from the client to the object s home server Along this best path routers direct the request toward a cache chosen among a collection of nearby translucent caches Unlike transparent caching which relies on routers to serve as TCP connection intermediaries translucent caches only use routers to get next hop cache information By doing away with TCP connection intermediaries translucent caches conserve the end to end argument based robustness
