# below is a list of the heads of HTTP responses (i.e with no content)
# these are used to drive the tests.
# Note that the last one does have a line of content, so we get more
# coverage because we switch filters for it
# If you want to add a head to test, put it as the first one,
# and add a $response_number == n and ok(1, foo) statement to the
# input subroutine n should be the number $response_number gets
# initialized to right now. Then increase the initialization and
# the number of tests planned.
