title: positive lookahead in htaccess
body: <p>I want to redirect from <code>domain.nl</code> to <code>domain.nl/nl</code> whenever a url is entered that does not contain <code>nl</code> after the <code>/</code><br>
  Here is my <code>.htaccess</code></p>
  
  <pre><code>RewriteCond %{HTTP_HOST}%{REQUEST_URI} ^domain\.nl/(?!nl).*$ [NC]
  RewriteRule ^(.*)$ http://domain.nl/nl [L,R=301]
  </code></pre>
  
  <p>Somehow it always matches even when putting in <code>domain.nl/nl</code> so I end up in an infinite loop of redirects.</p>
