this strikes me as a really bad idea, but as with many
really bad ideas, it's trivial to implement in perl. grab
the Geo::IP perl module, and then put
use Geo::IP;
sub get_country_code_from_ip ($) {
my $ip = shift;
our $geoip;
$geoip ||= new Geo::IP(GEOIP_STANDARD);
return $geoip->country_code_by_addr($ip);
}
in your startup perl module, then use,
${perl{get_country_code_from_ip}{$host_address}}
to obtain the country code in a string expansion.
