I want to redirect from `domain.nl` to `domain.nl/nl` whenever a url is entered that does not contain `nl` after the `/`  

Here is my `.htaccess`

```
RewriteCond %{HTTP_HOST}%{REQUEST_URI} ^domain\.nl/(?!nl).*$ [NC]
RewriteRule ^(.*)$ http://domain.nl/nl [L,R=301]

```

Somehow it always matches even when putting in `domain.nl/nl` so I end up in an infinite loop of redirects.
