1.3.6 Pass and Pipe modes

	  Requests which the can not or should not be handled by
	  Varnish can be either passed through or piped through to
	  the backend.
	
	  Passing acts on a per-request basis and tries to make the
	  connection to both the client and the backend reusable.

	  Piping acts as a transparent tunnel and whatever happens
	  for the rest of the lifetime of the client and backend
	  connection is not interpreted by Varnish.
