First book in new series focusing on web infrastructure issues. This is an area of major interest to folks managing large corporate networks who need to conserve bandwidth and ensure a high degree of security. For example, one of the biggest users of proxy server technology is Hewlett-Packard. H-P runs the largest corporate network in the world with over 100,00 nodes. Without a system of caching/proxy servers, H-P's Internet traffic would be unmanageable and unreliable. H-P uses the CERN proxy server developed by the author in local, regional and super caches.
