Redirect user when he has already validated some factors

Browse Source 
Example 1: The user has validated first factor when accessing a service
protected by basic auth. When he tries to access another service protected
by second factor, he is redirected to second factor step to complete
authentication.

Example 2: The user has already validated second factor. When he access auth
service, he is redirected either to /loggedin page that displays an "already
logged in" page or to the URL provided in the "redirect" query parameter.
