* Le cryptage de la connexion se fait au niveau du protocole TCP.
    * C'est une couche en dessous de HTTP.
    * Donc, le certificat et le traitement du cryptage sont faits avant HTTP.
* TCP ne connaît pas les "domaines", seulement les adresses IP.
    * L'information sur le domaine spécifique demandé se trouve dans les données HTTP.

 * Prevent leaking a cache item's InputStreams when metadata read fails.
 * Use a string to identify TLS versions in routes.
 * Add frame logger for HTTP/2.
 * Replacing `httpMinorVersion` with `Protocol`. Expose HTTP/1.0 as a potential protocol.
 * Use `Protocol` to describe framing.
 * Implement write timeouts for HTTP/1.1 streams.
 * Avoid use of SPDY stream ID 1, as that's typically used for UPGRADE.
 * Support OAuth in `Authenticator`.
