title: Add several GET parameters to urls
body: <p><br />
  I'm trying to use several GET parameters in a URL.</p>
  
  <p>For example <code>logout-user</code> and <code>clear-cart</code> - is it possible to do something like: </p>
  
  <pre><code>/?clear-cart&amp;&amp;logout-user
  </code></pre>
  
  <p>What would be the correct way to do it? 
  I'm using WordPress.<br /></p>
