Squid is a caching web proxy.  It replaces the cache of your browser
with one that's:

  - Centralized.  Multiple browsers, users, and/or hosts can hit the
    same cache.

  - Specialized.  Squid is a cache.  It's not a browser / mailer /
    newsreader / HTML editor / toaster.  It's a cache.  It specializes
    in being fast and configurable to your needs.

  - Bigger.  Throw as much storage at the cache as you can spare.  I run
    about 1.5 GB on my firewall (the storage is otherwise unused).
    Memory and storage are offloaded from my workstations.

  - Portable.  Put the cache where it's useful, needed, and/or out of
    the way.  Again, mine's on a firewall.

To create a transparent cache, you'll create a NAT rule for your
firewall to redirect INTERNAL traffic bound for EXTERNAL sites on PORT
80 to the PROXY listener port.

I actually do this under OpenBSD, my rule is:

    rdr dc0 0.0.0.0/0 port 80 -> 192.168.0.1 port 8080

Cheers.
