title: Paypal never redirects to my website after transaction
body: <p>I have used Paypal integration in my asp.net application and want Paypal to redirect back to my specified page that I have given in its url:</p>
  
  <pre><code>//Success return page url
          redirecturl += "&amp;return=" +
            ConfigurationManager.AppSettings["SuccessURL"].ToString();
  
          //Failed return page url
          redirecturl += "&amp;cancel_return=" +
            ConfigurationManager.AppSettings["FailedURL"].ToString();
  
          Response.Redirect(redirecturl);
  </code></pre>
  
  <p>But it never returns back to my website, instead it just shows "Thanks for your order" with Paypal url in address bar.

  <p>What should I do to force it return to my website's page after completing the transaction?</p>
