+.. admonition:: Be careful with the order of decorators
+
+    When ``condition()`` returns a conditional response, any decorators below
+    it will be skipped and won't apply to the response. Therefore, any
+    decorators that need to apply to both the regular view response and a
+    conditional response must be above ``condition()``. In particular,
+    :func:`~django.views.decorators.vary.vary_on_cookie`,
+    :func:`~django.views.decorators.vary.vary_on_headers`, and
+    :func:`~django.views.decorators.cache.cache_control` should come first
+    because :rfc:`RFC 7232 <7232#section-4.1>` requires that the headers they
+    set be present on 304 responses.
