keeps meta data and especially hot objects cached in RAM,
caches DNS lookups, supports non-blocking DNS lookups, and implements
negative caching of failed requests.
supports SSL, extensive access controls, and full request

consists of a main server program squid, a Domain Name System
lookup program dnsserver, some optional programs for rewriting
requests and performing authentication, and some management and client
tools. When squid starts up, it spawns a configurable number of
dnsserver processes, each of which can perform a single, blocking
Domain Name System (DNS) lookup. This reduces the amount of time the
cache waits for DNS lookups.
