In Forms authentication, on session timeout instead of going to login.aspx is it possible to redirect to a custom page based on the role?

Similarly on logout,redirecting to a custom page?

For Eg: For studentRole - redirect to StudentTimedOut.aspx/StudentLoggedout.aspx

           For TeacherRole  -  redirect to TeacherTimedOut.aspx/TeacherLoggedOut.aspx

 Please help !

I think you have to persist the Logged in user type as at this instance you don't have the Session, so you can keep this information in cache or in some static variable, so while checking the session == null (means user session is expired), you can put one more condition, like userType=="Student"
