 might be better with separate first/between timeouts like we have on the
 backend side.

 It might be important to update the documentation within:

 param.show -l
 sess_timeout               60 [seconds]
                            Default is 5
                            Idle timeout for persistent sessions. If a HTTP
                            request has not been received in this many
                            seconds, the session is closed.

 This explanation is not entirely correct - it is also the maximum time
 spent waiting for a client to send its HTTP request to Varnish.
