Bit difficult but could be interesting. Herein I try to explain it better:


externaldomain could be blocked as an externernaldomain is not site, so
unsafe redirection may not take place.
However site could try to resolve the externernaldomain sub domain as an
additional security check.

CSRF the login funciontality would be good for having more power and
forcing load balancers to perform login faster to trigger the DNS
resolution from the internal server.
