Remarks

The methods create an encrypted string from the authentication cookie and append it to the redirecting URL of the originating request. A client-side redirect is then issued for that URL. This can be used to work around the limitations of certain mobile devices that either do not support cookies, or support cookies that are too small for storing authentication information in a secure manner.
