title: How can I prevent Backspace from taking me back to the previous page while I use the login box
body: <p>the login box is in the header of the website, availalbe on all pages.
  I'm using a javascript : </p>
  
  <pre><code>&lt;script type="text/javascript" language="javascript"&gt;
         history.forward();
  </code></pre>
  
  <p>
  Which solves the issue of the backspace in the login box.
  But while I'm browsing the rest of the website, I can use backspace to see the previous page, I'd have to use the navigation menu only. How can I solve that issue ?</p>
