  * *2.8*: The `active_n` option was added.
  * *2.8*: The `max_received_frame_rate` default value has

  linger_timeout (1000)::
  
  Time in ms that Cowboy will wait when closing the connection. This is
  necessary to avoid the TCP reset problem as described in the
  https://tools.ietf.org/html/rfc7230#section-6.6[section 6.6 of RFC7230].
  In HTTP/2's case the GOAWAY message might also be lost when
  closing the connection immediately.
  
  logger (error_logger)::
  
  The module that will be used to write log messages.
