      If pipelining is active on the connection (because both the pipeline
      option is true and the connection is known to be an HTTP/1.1 server),
      then requests will be pipelined into the connection awaiting their
      response. If not, they will be queued awaiting a response to the
      previous before sending the next.

    max_connections_per_host > 1

      In this mode, there can be more than one connection per host. If a
      new request is made, it will try to re-use idle connections if there
      are any, or if they are all busy it will create a new connection to
      the host, up to the configured limit.

    max_connections_per_host = 0

      In this mode, there is no upper limit to the number of connections
      per host. Every new request will try to reuse an idle connection, or
      else create a new one if all the existing ones are busy.

    These modes all apply per hostname / server port pair; they do not
    affect the behaviour of connections made to differing hostnames, or
    differing ports on the same hostname.

PARAMETERS

    The following named parameters may be passed to new or configure:
