  /** Returns bytes of a request header for sending on an HTTP transport. */
  fun writeRequest(
    headers: Headers,

    socket.sink.writeUtf8(requestLine).writeUtf8("\r\n")

De esta manera, puedes crear un token con una expiración de, digamos, 1 semana. Y luego, cuando el usuario regresa al día siguiente con el token, sabes que el usuario todavía está registrado en tu sistema.

Alerting with prometheus is two step process. First we setup alerts in Prometheus server and then we need to send alerts to the AlertManager.

API changes
-----------

We make changes to Guava's public [APIs][], including adding new APIs, very
carefully. Because of this, if you're interested in seeing a new feature in
Guava, the best approach is to create an [issue][] (or comment on an existing
issue if there is one) requesting the feature and describing specific use cases
for it.

 * doesn't include the motivating request's HTTP headers or even its full URL; only the target
 * server's hostname is sent to the proxy.
 *
 * Prior to sending any CONNECT request OkHttp always calls the proxy authenticator so that it may
 * prepare preemptive authentication. OkHttp will call [authenticate] with a fake `HTTP/1.1 407

			/// Enable keep-alive

				_ = unix.SetsockoptInt(fd, unix.SOL_SOCKET, unix.SO_KEEPALIVE, 1)

				// The time (in seconds) the connection needs to remain idle before
				// TCP starts sending keepalive probes
				_ = syscall.SetsockoptInt(fd, syscall.IPPROTO_TCP, syscall.TCP_KEEPIDLE, 15)

				// Number of probes.
				// ~ cat /proc/sys/net/ipv4/tcp_keepalive_probes (defaults to 9, we reduce it to 5)

Dessa forma, você pode criar um token com um prazo de expiração, digamos, de 1 semana. E então, quando o usuário voltar no dia seguinte com o token, você sabe que ele ainda está logado no seu sistema.
