This release of Squid is pre-configured to act as an HTTP accelerator.
As such, it runs on port 80 and caches requests to the 'real' server
running on port 8080. These parameters can be configured by editing
/usr/local/squid/etc/squid.conf. In addition, the Apache web server
contained elsewhere in this distribution is configured by default to
run on port 8080. Thus, you can install these preconfigured versions
of Squid and Apache and they should 'just work'.

If you already have a server running on port 80 (e.g. the Netscape FastTrack
server), you will need to disable that or reconfigure Squid prior to starting
Squid. In addition to the Squid binary distribution, this package also
contains the Squid User's Guide which has been installed in the Apache
web server's default document root (/usr/local/lib/apache/share/htdocs/squid).
To access it, after installing Squid and Apache, open :
http://your.host.name/squid/

Squid has been configured to start automatically every time the system goes 
multi-user. To start Squid now, execute the command '/etc/squid start' after
the successful completion of this installation. "
