country based redirection in htaccess

Question

I want to redirect this url :

www.example.com/index.php?cn=us

to

www.example.com/us/ 

is it possible in htaccess? and how?

Answer 1

Try this:

RewriteEngine On
RewriteRule ^([a-z]{2})/?$ index.php?cn=$1

And this shows this works with any two letter country code

index.php

<?php
echo $_GET['cn'];
?>
