25782	Discourage usage of cache_page decorator with UpdateCacheMiddleware (or make middleware ignore decorated views)	Serhiy	Wassef Ben Ahmed	"If django.middleware.cache.UpdateCacheMiddleware is active and some view is decorated with the cache_page that overrides cache alias, this view will be cached in both caches, first time by cache_page and then by the middleware. Well, at least it will try. And fail if the default cache is memcached and the view response is bigger than its' maximum entry size. While filebased cache will work and even create the cache entry. This way first user to visit when there are no entry in cache will get error instead of data.
So, I guess there should be some warning about this in the docs.
Ideally, middleware should ignore views with overridden cache alias, maybe by means of checking headers like in case of the cache_control decorator."	Cleanup/optimization	assigned	Documentation	dev	Normal			Ülgen Sarıkavak	Accepted	1	0	0	1	0	0
