Proxy Caches

    Here are all the available proxy cache systems and services known to me. Note that features and performance vary, such as which net protocols (such as HTTP, FTP, GOPHER, etc.) are supported for caching, and which inter-cache communication methods are used (ICP, CARP, WCCP).

    Thanks to Duane Wessels' Information Resource Caching FAQ for many of the entries on this list. There is also a table comparing some of the commercial systems available.
