Get the userService object from the UserServiceFactory class in
google app engine api. Invoke the getCurrentUser() method in
userService object. Check whether the user is alive or not. if user
is alive call the createLogoutURL(pass_your_ logout_ url), or call the
createLoginURL(pass_your _login _url) in UserService object.
