``response`` may also be an :class:`~django.http.StreamingHttpResponse`
object.
Unlike :class:`~django.http.HttpResponse`,
:class:`~django.http.StreamingHttpResponse` does not have a ``content``
attribute. As a result, middleware can no longer assume that all responses
will have a ``content`` attribute. If they need access to the content, they
must test for streaming responses and adjust their behavior accordingly::
if response.streaming:
response.streaming_content = wrap_streaming_content(response.streaming_content)
else:
response.content = wrap_content(response.content)
``streaming_content`` should be assumed to be too large to hold in memory.
Middleware may wrap it in a new generator, but must not consume it.
