Squid in 5 minutes

Why Squid? Why only five minutes?

There are many great tools that Squid has to offer, but when I need to redirect http traffic to a caching server for performance increases or security, squid’s my pick. Squid has built in proxy and caching tools that are simple, yet effective.

I recently used Squid for a secure subnet that did not allow outgoing port 80 http access to external IP addresses. Many organizations will block external port 80 access at the router level. This is a great way to eliminate a huge security hole, but a headache when a systems administrator needs to reach the outside world temporarily to download a file. Another scenario: redirect all computers in a home network to a local caching server to increase website query performance and save on bandwidth.
