- 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 supports SSL, extensive access controls, and full request logging.
- By using the lightweight Internet Cache Protocol, Squid caches can be
- arranged in a hierarchy or mesh for additional bandwidth savings.
