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.
Squid 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.
My intent is to run a Squid box with Squid Guard in order to restrict access to specific resources on the interweb and track access from the computers in my pre-k classrooms.
My secondary goal is to force internet access across my DSL connections to be directed thru a proxy server in order to manage access from a central location. Currently I have each Zywall router setup for content filtering. This is a pain, so I'm trying to get more granular on my control. I am teh interweb nazi
