 * Rack::MMGeoip pins a MMGeoipProxy to your environment and does the loopup lazy when you first access a geoip property.
 * Rack::MMGeoip looks for the standard geoip headers and wraps their access, too. So if you're adding these header with mod_geoip in Apache or with http_geoip_module in NGinX these headers are used. So you can use this middleware even in production without compromising performance if NGinX or Apache already adds these headers.

+geo.city        # => "Konstanz"

+geo.region_name # => "Baden-Wurttemberg"

 h2. Performance
 
 Rack::MMGeoip uses the geoip gem. In my tests this lib did about 17_000 lookups in about 17 seconds on my MBP, so you probably lose one ms per request when using the middleware.
