it's returned directly.

can be used to modify the response depending
on how the request looked like.

def make_conditional(self, request_or_environ):
"""Make the response conditional to the request. This method works
best if an etag was defined for the response already. The `add_etag`
method can be used to do that. If called without etag just the date
header is set.
This does nothing if the request method in the request or environ is
anything but GET or HEAD.
It does not remove the body of the response because that's something
the :meth:`__call__` function does for us automatically.
Returns self so that you can do ``return resp.make_conditional(req)``

used to make the response conditional
against.
