/**
|
|
* Isolir Redirector
|
|
* Menerima HTTP request dari pelanggan terisolir (host/path apa pun) dan
|
|
* mengalihkan (302) ke halaman isolir dinamis milik portal billing.
|
|
*
|
|
* Dipakai oleh rule NAT MikroTik: dst-address=<server> to-ports=<PORT ini>.
|
|
* Karena edge publik (Traefik/NetBird) melakukan 308 ke HTTPS dan TLS hanya
|
|
* melayani domain kanonik, DNAT polos tidak cukup — harus redirect ke URL kanonik.
