NAME
    Plack::Middleware::GeoIP - Find country and city of origin of a web
    request

SYNOPSIS
      # with Plack::Middleware::RealIP
      enable 'Plack::Middleware::RealIP',
          header => 'X-Forwarded-For',
          trusted_proxy => [ qw(192.168.1.0/24 192.168.2.1) ];
      enable 'Plack::Middleware::GeoIP',
          GeoIPDBFile => [ '/path/to/GeoIP.dat', '/path/to/GeoIPCity.dat' ],
          GeoIPEnableUTF8 => 1;

DESCRIPTION
    Plack::Middleware::GeoIP is a loose port of the Apache module mod_geoip.
    It uses Geo::IP to lookup the country and city that a web request
    originated from.

    All requests are looked up and GEOIP_* variables are added to PSGI
    environment hash. For improved performance, you may want to only enable
    this middleware for specific URL's.

    The following PSGI environment variables are set by this middleware:

    GeoIP Country Edition:

    GEOIP_COUNTRY_CODE, GEOIP_COUNTRY_CODE3, GEOIP_COUNTRY_NAME,
    GEOIP_CONTINENT_CODE

    GeoIP City Edition:

    GEOIP_COUNTRY_CODE, GEOIP_COUNTRY_CODE3, GEOIP_COUNTRY_NAME,
    GEOIP_CONTINENT_CODE, GEOIP_LATITUDE, GEOIP_LONGITUDE, GEOIP_TIME_ZONE,
    GEOIP_REGION, GEOIP_REGION_NAME, GEOIP_CITY, GEOIP_POSTAL_CODE,
    GEOIP_METRO_CODE, GEOIP_AREA_CODE
