I have my registration controller setup to only allow anonymous users

Code:
@Controller
@PreAuthorize("isAnonymous()")
public class RegistrationController {
   //snip
}
this however throws a 403, as expected, when an authorized user attempts to access this page.

I am trying to find what handler/intercepter/filter I must reimplement, so in these cases, I can redirect the user to their "account" page.

spring-security-3.1.1.RELEASE

Thanks in advance
