Different Drupal front page from different country

[J`Surf]

I have a drupal site, and i want to redirecting visitors to a different page based on the country.I have this code:\[code\]require_once "Net/GeoIP.php";$geoip = Net_GeoIP::getInstance("Net/GeoIP.dat");try { $geocode = $geoip->lookupCountryCode($_SERVER['REMOTE_ADDR']);} catch (Exception $e) { $geocode = 'EN';}switch ($geocode) { case 'HU': header('Location: http://www.example.com/hu'); break; case 'GB': header('Location: http://www.example.com/en'); break; case 'AT': header('Location: http://www.example.com/at'); break; case 'CY': header('Location: http://www.example.com/cy'); break; case 'DE': header('Location: http://www.example.com/de'); break; case 'NL': header('Location: http://www.example.com/nl'); break; case 'CH': header('Location: http://www.example.com/ch'); break; case 'ES': header('Location: http://www.example.com/es'); break; case 'US': header('Location: http://www.example.com/us'); break; default: header('Location: http://www.example.com/en');}\[/code\]This works well on plain php file. How can i this in drupal?How can i redirect the visitors to the proper node?
