# 0-RTT

Para reducir el tiempo necesario para establecer una nueva conexión, un cliente que se ha conectado previamente a un servidor puede almacenar en caché ciertos parámetros de esa conexión y posteriormente establecer una conexión **0-RTT** con el servidor. Esto permite al cliente enviar datos inmediatamente sin esperar a que se complete el handshake.
