  <p>I am logs in my application by using dotnetopenid provider suppose google. </p>
  
  <p>At the time of logout I am ending the my application user's session by FormsAuthentication.SignOut(); but if I am not closing the browser and logs in using google it will not ask me for id-password and land me on secured page of my apllication.</p>
