@ -107,15 +107,18 @@ middleware is always called on every response.
|
||||
``request`` is an :class:`~django.http.HttpRequest` object. ``response`` is the
|
||||
:class:`~django.http. HttpResponse` object returned by a Django view.
|
||||
|
||||
``process_response()`` should return an :class:`~django.http. HttpResponse`
|
||||
``process_response()`` must return an :class:`~django.http. HttpResponse`
|
||||
object. It could alter the given ``response``, or it could create and return a
|
||||
brand-new :class:`~django.http. HttpResponse`.
|
||||
|
||||
Remember that your middleware will not be called if another middleware object
|
||||
returns a response before you. But unlike ``process_request()`` and
|
||||
``process_view()``, during the response phase the classes are applied in reverse
|
||||
order, from the bottom up. This means classes defined at the end of
|
||||
:setting:`MIDDLEWARE_CLASSES` will be run first.
|
||||
Unlike the ``process_request()`` and ``process_view()`` methods, the
|
||||
``process_response()`` method is always called, even if the ``process_request()``
|
||||
and ``process_view()`` methods of the same middleware class were skipped because
|
||||
an earlier middleware method returned an :class:`~django.http. HttpResponse`
|
||||
(this means that your ``process_response()`` method cannot rely on setup done in
|
||||
``process_request()``, for example). In addition, during the response phase the
|
||||
classes are applied in reverse order, from the bottom up. This means classes
|
||||
defined at the end of :setting:`MIDDLEWARE_CLASSES` will be run first.
