I have a website that is currently in Dutch. Now I want to make the website multi-language starting with English. I am not that good at .htaccess files and the information on the web is quite confusing.

The website I have now uses pretty urls, so all my urls look like this:

http://mydomain.com/about/info http://mydomain.com/about/contact

The code that I use for that is the following:

<IfModule mod_rewrite.c>
    RewriteEngine on
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-l
    RewriteRule ^(.*)$ index.php?rt=$1 [L,QSA]
</IfModule>

I really do not know what this means, esp the [L,QSA]. But it's ok, it works for now.

But now I want to add a default redirect to the code. So it becomes as follow

http://mydomain.com becomes http://mydomain.com/nl

I assume all my old links http://mydomain.com/about/info will not work anymore, but that is a step I am willing to take.

Can someone please help me with this code. I have seen a lot of peaces of code, but I can not find the right one.
