     ==============================
     ip based geographic lookups...
     ==============================
     -----------------
     Module: mod_geoip
     -----------------
     .. contents:: Table of Contents
     Requirements
     ============
     :Packages: GeoIP C API & Library (http://www.maxmind.com/download/geoip/api/c/)
     Overview
     ========
     mod_geoip is a module for fast ip/location lookups. It uses MaxMind GeoIP /
     GeoCity databases.
     If the ip was found in the database the module sets the appropriate
     environments variables to the request, thus making other modules/fcgi be
     informed.
     .. note::
       Currently only country/city databases are supported because they have a free
       version that i can test.
     Configuration Options
     ========================
     mod_geoip uses two configuration options.
 ) geoip.db-filename = <path to the geoip or geocity database>
 ) geoip.memory-cache = <enable|disable> : default disabled
     if enabled, mod_geoip will load the database binary file to
     memory for very fast lookups. the only penalty is memory usage.
     .. note::
      mod_geoip will determine the database type automatically so if you enter
      GeoCity databse path it will load GeoCity Env.
     Environment
     ===========
     Every database sets it's own ENV:
     GeoIP (Country):
     ----------------
     ::
      GEOIP_COUNTRY_CODE
      GEOIP_COUNTRY_CODE3
      GEOIP_COUNTRY_NAME
     GeoCity:
     --------
     ::
      GEOIP_COUNTRY_CODE
      GEOIP_COUNTRY_CODE3
      GEOIP_COUNTRY_NAME
      GEOIP_CITY_NAME
      GEOIP_CITY_POSTAL_CODE
      GEOIP_CITY_LATITUDE
      GEOIP_CITY_LONG_LATITUDE
      GEOIP_CITY_DMA_CODE
      GEOIP_CITY_AREA_CODE
     Examples
     ========
     mod_geoip + php
     ---------------
     when using fastcgi (not only php) you can access mod_geoip env and do as you
     please. this example just prints all mod_geoip envs to the client, html.
     Config-file ::
      geoip.db-filename = "/your-geoip-db-path/GeoCityLite.dat"
      geoip.memory-cache = "enable"
     index.php ::
      <?php
              $country_code = $_SERVER['GEOIP_COUNTRY_CODE'];
              $country_code3 = $_SERVER['GEOIP_COUNTRY_CODE3'];
              $country_name = $_SERVER['GEOIP_COUNTRY_NAME'];
              $city_region = $_SERVER['GEOIP_CITY_REGION'];
              $city_name = $_SERVER['GEOIP_CITY_NAME'];
              $city_postal_code = $_SERVER['GEOIP_CITY_POSTAL_CODE'];
              $city_latitude = $_SERVER['GEOIP_CITY_LATITUDE'];
              $city_long_latitude = $_SERVER['GEOIP_CITY_LONG_LATITUDE'];
              $city_dma_code = $_SERVER['GEOIP_CITY_DMA_CODE'];
              $city_area_code = $_SERVER['GEOIP_CITY_AREA_CODE'];
              echo "<html>\n<body>\n\t<br>\n";
              echo 'Country Code: ' . $country_code . '<br>';
              echo 'Country Code 3: ' . $country_code3 . '<br>';
              echo 'Country Name: ' . $country_name . '<br>';
              echo '<br>';
              echo 'City Region: ' . $city_region . '<br>';
              echo 'City Name: ' . $city_name . '<br>';
              echo 'City Postal Code: ' . $city_postal_code . '<br>';
              echo 'City Latitude: ' . $city_latitude . '<br>';
              echo 'City Long Latitude: ' . $city_long_latitude . '<br>';
              echo 'City DMA Code: ' . $city_dma_code . '<br>';
              echo 'City Area Code: ' . $city_area_code . '<br>';
              echo "</html>\n</body>";
      ?>
     country based redirect
     ----------------------
     Config-file ::
      $HTTP["host"] =~ "www.domain.com" {
          url.rewrite = ( "" => "/redirect.php")
+     }
     redirect.php ::
      <?php
             $country_code = $_SERVER['GEOIP_COUNTRY_CODE'];
             header ('Location: http://' . $country_code . '.domain.com/');
      ?>
     .. note::
      Currently it is not possible to redirect based on mod_geoip directly in
     lighttpd config file. But i believe with the relase of lighttpd mod_magnet
     it would be. (mod_magnet will be available in lighttpd 1.4.12+)
