    Environment variables are a series of hidden values that the web server sends to every CGI you run. Your CGI can parse them and use the data they send. Environment variables are stored in a hash called %ENV.

    For example, $ENV{'HTTP_HOST'} will give the hostname of your server.

    #!/usr/bin/perl

print "Content-type:text/html\n\n";
print <<EndOfHTML;
<html><head><title>Print Environment</title></head>
<body>
EndOfHTML

foreach my $key (sort(keys %ENV)) {
    print "$key = $ENV{$key}<br>\n";
}

print "</body></html>";
