Ынструкцыа
1. Сначала надо скачать файл:
http://www.maxmind.com/download/geoip/database/GeoIP.dat.gz,
распаковать его, переименовать "GeoIP.dat" в "geoip.dat" и залить на хост строго в бинарном режиме, туда где будет скрипт редиректа лежать.
2. Скопировать код в "блокноте" и сохранить в файл с расширением *.php.
3. Открыть сохраненный файл, тоже в "блокноте", и заменить "http://url.good/" на URL-адрес куда будем направлять хороших пользователей из платежеспособных стран, а "http://url.bad/" на URL-адрес для беспорточных халявщиков.
4. Залить файл в текстовом режиме(ASCII) на хост к файлу "geoip.dat".
5. Наслаждаться результатом
P.S. Файл "geoip.dat" желательно обновлять хотя бы раз в месяц, как указано в п.1
