          <p>Click the button to make a call to the server using LiveConnect.
          This example will only work when run in a Web server environment. You'll need
          to change the URL <code>http://localhost/reflectpost.php> to point to a valid
          file on the server. If this works, you should see the same values that
          were POSTed to the URL.</p>
