Geo IP client

Sometimes you might want to find out location of where your web traffic is coming from. In that case you might want to look into the access log generated by your web server, it will give you ip address of the client. ONce you have the client's ip you can use GeoIP database to look up city, state, country for that ip. You can download the sample project from here This is how a sample log line looks like
