text: # This handler is designed to verify that UAs correctly discard the body of
  # responses to HTTP HEAD requests. If the response body is written to a
  # separate TCP packet, then this behavior cannot be verified. This handler uses
  # the response writer to ensure that the body is transmitted in the same packet
  # as the headers. In this way, non-conforming UAs will consistently fail the
