Syntax:
Geoip_city path/to/db. dat;
Default:None
Context:
HttpThe directive indicates the path to the. dat file used for determining countries, regions and cities from IP-address of the client. When set the module makes available the following variables:
$ Geoip_city_country_code;-two-letter country code, for example, "RU", "US ". $ geoip_city_country_code3;-three-letter country code, for example, "RUS", "USA ". $ geoip_city_country_name;-the name of the country, for example, "Russian Federation", "United States ". $ geoip_region;-the name of region (province, region, state, province, federal land, and the like), for example, "Moscow City", "DC ". $ geoip_city;-the name of the city, for example, "Moscow", "Washington ". $ geoip_postal_code;-postal code.
