title: MVC3 :a required anti-forgery token was not supplied or was invalid
body: <p>I redirect a page from web form page(<strong>profile.aspx</strong>) to MVC view (<strong>signin.aspx</strong>). In MVC controller, I have <code>[ValidateAntiForgeryToken]</code> to get token information, but when I submit MVC view, I get <strong>'a required anti-forgery token was not supplied or was invalid'</strong> message. If I remove <code>[ValidateAntiForgeryToken]</code>, there is no more error message, but I lose my token information.
  I do need all those token information for validation. So how can I fix this kind of issue?
  Thanks.</p>
