title: Redirect without changing the url in the adressbar
body: <p>So, i want address <code>chat.example.tk</code> to display the contents of <code>example.tk/chat</code>, but in a way that the address bar still displays <code>chat.example.tk</code></p>
  <p>This is the <code>.htaccess</code> code i tried:</p>
  <pre><code>RewriteEngine on
  RewriteCond %{HTTP_HOST} ^chat.example.tk
  RewriteRule ^(.*)$ http://example.tk/chat/$1 [L,NC,QSA]
  </code></pre>
