Summary

Squid is a high-performance proxy caching server for Web clients,

supporting FTP, gopher, and HTTP data objects. Unlike traditional

caching software, Squid handles all requests in a single,

non-blocking, I/O-driven process. Squid 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.

Squid consists of a main server program squid, a Domain Name System

lookup program (dnsserver), a program for retrieving FTP data

(ftpget), and some management and client tools.
