This release of Squid is pre-configured to act as a cacheing proxy server.
As such, it runs on port 3128. These parameters can be configured by editing
/usr/local/squid/etc/squid.conf. 

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/htdocs/squid).
To access it, after installing Squid and Apache, open :
http://your.host.name/squid/
