If your page is HTML, which is what my page_visited = 'http://companypage/index.html'; leads me to believe.

You could do something like:

#! /usr/bin/perl -T
use strict;

use CGI;
my $cgi = new CGI;
my $page = $cgi->param('page');
my %mail = ( To      => 'jones@company.com',
             From    => 'smith@company.com',
             Subject => "$page visited",
             Message => "$page was visited",
             smtp    => '111.222.333.444'
           );
&sendmail(\%mail);

print $cgi->header();
open(FILE, "/path/to/html/$page.htm");
print while(<FILE);
close(FILE);

This is a simple example, I would look into using HTML::Template instead.
