El **proxy** intercepta el request original del cliente y añade los *headers* especiales de reenvío (`X-Forwarded-*`) antes de pasar el request al **application server**.

Estos headers preservan información sobre el request original que de otro modo se perdería:

* **X-Forwarded-For**: La IP original del cliente
* **X-Forwarded-Proto**: El protocolo original (`https`)
* **X-Forwarded-Host**: El host original (`mysuperapp.com`)

            oout.writeObject(original);
