{{{ #!rst ============================== 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. 1) geoip.db-filename = 2) geoip.memory-cache = : 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 database 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 :: \n\n\t

But i believe with the release of lighttpd mod_magnet it would be. (mod_magnet will be available in lighttpd 1.4.12+) Downloads ========= mod_geoip.c (http://trac.lighttpd.net/trac/attachment/wiki/Docs/ModGeoip/mod_geoip.c) }}}
