But this example is still valid and it shows how to interact with the internal components.

We can also use this same approach to access the request body in an exception handler.

Luego, usando el certificado, el cliente y el TLS Termination Proxy **deciden cómo encriptar** el resto de la **comunicación TCP**. Esto completa la parte de **Handshake TLS**.
