I&#039;m sending an email to my users, with a link to one of the protected pages in my application. this message contains a link, with an encrypted email and password in the query string. When the user clicks on that link, I would like the application to authenticate the user using the email/password combination and send the user directly to the protected page without having to login.<BR>If in a previous session, the user opted to "remember" the login, and the authentication cookie is found, the user gets redirected to the protected pages without logging in.<BR>My problem is when there is no cookie. I got to verify the user credentials and create an authentication cookie, inside Global.asax&#039;s AuthenticateRequest event , but i couldn&#039;t add it to the response object cause this doesn&#039;t exist yet at this point.<BR>I would appreciate any suggestions. Thanks in advance.<BR>J
