[edit] Synopsis

This module has been replaced by the official NginxHttpGeoIPModule since Nginx 0.7.63/0.8.6.

Please use this module only for Nginx 0.7.62 or earlier.

The Nginx GeoIP module is based on the original Geo module, the difference being that it is not being controlled by a piece of config, but makes use of the MaxMind GeoIP binary API natively. It provides for fast lookups from both the binary GeoLite Country and GeoIP Country databases.

One of the advantages to use the binary databases and API is getting automated updates from MaxMind through the geoipupdate utility. This is also the reason why SPIL GAMES wrote this module.

Example usage:

geoip_country_file /absolute/path/to/GeoIP.dat;
location /geoip/ {
  rewrite .* /?country=$geoip_country_code;
}
