title: .htaccess RewriteRule exclude folder
body: <p>I've made a TLP system for PHP with .htaccess. And I want to exclude the /admin folder (in root folder).
  I've got this .htaccess:</p>
  
  <pre><code>RewriteEngine On
  RewriteRule ^(|/)$ index.php?url=$1
  RewriteRule ^([a-zA-Z0-9_-]+)(|/)$ index.php?url=$1
  </code></pre>
  
  <p>When I enter the /admin directory, it says: /admin/?url=admin.
  But I don't want it to request the ?url=admin.</p>
  
  <p>Does somebody know how to exclude the /admin folder?
  Many thanks!</p>
