title: Page isn't reloaded after clicking back button in browser
body: <p>When clicking the back button in my browser, the url is changed but the page content is stale/cached.</p>
  
  <p>I've tried using:</p>
  
  <pre><code>def set_no_cache
    response.headers["Cache-Control"] = "no-cache, no-store, max-age=0, must-revalidate"
    response.headers["Pragma"] = "no-cache"
    response.headers["Expires"] = "Fri, 01 Jan 1990 00:00:00 GMT"
  end
  </code></pre>
  
  <p>but it doesn't seem to help.</p>
  
  <p>Would be glad for any thoughts/suggestions on how to get this to work properly...</p>
