MobileFormsAuthentication.RedirectFromLoginPage telling the user that the current page has been moved

I use MobileFormsAuthentication.RedirectFromLoginPage. everything works fine except that it tells the user that the current page, which is the login page, has been moved and ask the user whether to go to the new location. the user has to press cancel in order to get to the redirected page. can i separate the authentication and redirecting? after the authentication i would use Server.Transfer() to get the user to another page. PLEASE HELP!
