        Test for <i><a href="https://bugs.webkit.org/show_bug.cgi?id=18401">bug 18401</a></i>
        Apparent caching between form submits.
    </p>
    <p>
      In this test the main page is loaded in a frameset, which sets the value of an input field
      in a form and has an iframe, which loads a page which submits the form.  The form's target
      is the main page.  When the form is reloaded it should not have the value that was set
      before the submission.
