title: redirecting to a specific page when clicking browser's back button
body: <p>it's a bit of a nooby question, but there it goes:<br>
  i have a site where the user can only navigate from page to page via next and back buttons. i.e there is a wizard the user must follow. part of the wizard includes different pages and part includes the same page but with changing divs (but from user experience its a different page).<br>
  i would like to simply redirect the user to the first page of the wizard, whenever he clicks on the browser's back button.<br>
  if possible and simple, i prefer doing so without the use of (yet another) plugin.</p>
  
  <p>thanks.</p>
