title: Redirect after a few seconds to "Thank you" page
body: <p>The second day I am playing with integrating PayPal to my website. I am trying to obtain the following behavior:</p>
  
  <ul>
  <li>the user click on the BUY link => is redirected to PAYPAL page (that's ok)</li>
  <li>the user finished payment, on the PayPal website is displayed "Thank you" page</li>
  <li>after 10 seconds is user redirected to "Thank you" page on my website</li>
  <li>to user's PayPal email is sent information about the product he bought</li>
  </ul>
  
  <p>This is what I try to implement, but unfortunatelly I still can't find the right way to do it... My app is in Ruby on Rails, currently I am working with Sandbox and use PayPal Payments Standard.</p>
  
  <p>Could you please give me some advise/tip/link, how to implement this behavior?</p>
