body: <p>How can I simulate page refresh (F5) with CasperJS ? </p>
  
  <p>I'm trying to simulate F5 because I want to test if my Cookie Manager works fine ( <strong>the first time must not</strong> set a certain cookie, <strong>the second time it must</strong> ).</p>
  
  <p>Calling two times <code>casper.start(url)</code> doesn't work.</p>
