1. Modify your httpd.conf to allow access to HTML output like follow:
        Alias /squidreport $HTMLDIR
        <Directory $HTMLDIR>
            Options -Indexes FollowSymLinks MultiViews
	    AllowOverride None
            Order deny,allow
            Deny from all
            Allow from 127.0.0.1
        </Directory>
2. If necessary, give additional host access to SquidAnalyzer in httpd.conf.
   Restart and ensure that httpd is running.
3. Browse to http://my.host.dom/squidreport/ to ensure that things are working
   properly.
4. Setup a cronjob to run squid-analyzer daily:

     # SquidAnalyzer log reporting daily
     0 2 * * * $BINDIR/squid-analyzer > /dev/null 2>&1

or run it manually. For more information, see $DOCDIR/README file.
