Do you know any "url shortener script" that redirect based on country?

Hi, I need one of this script but i found that they dont have the option of geo redirect.
Do you know any alternative? Open source or cheap. Many thanks!

Firstly you should know how do you want to know where is your user located and then what kind of back end are you using, anyways if you want to do it based on https headers you'd need something like this for php

<?php
$COUNTRY = $_SERVER['HTTP_ACCEPT_LANGUAGE']; //get the header
if( strpos($COUNTRY,"en-us") ) { //string to match
header("Location: http://yourpageforUSvisitors.com"); //Redirect
}
?>

I believe you can also do this via nginx or apache if you are using any of those and it should be more efficient, also notice you are redirecting via their browser language so anyone can fool your system really easy

Anyways I dont remember really well php as i dont use it anymore so if anyone notices any mistake let me know
