About CacheLink

CacheLink dramatically improves Internet and intranet performance by retrieving frequently viewed Web pages from other CacheLink users in a company's LAN instead of from the Internet. It complements the browser caches in each PC by efficiently linking them together into a single cache pool for all PCs. Performance measurements show CacheLink delivers Web cache hits, on average, 40 times faster than a non-cached 56K shared-modem. CacheLink users spend less time waiting for Web content while also freeing up Internet bandwidth, resulting in more available capacity.
