title: How to redirect all requests to index.php and keep the other GET params?
body: <p>Here's what I've got so far:</p>
  
  <pre><code>RewriteEngine on
  
  RewriteCond %{REQUEST_FILENAME} !index.php
  RewriteRule .* index.php?url=$0 [L]
  </code></pre>
  
  <p>But when I go to soemthing like <code>/a?b=c</code> and then inspect the GET params, I only get <code>a</code> for <code>url</code>, and <code>b</code> is lost. How can I retain that?</p>
