Why doesn't Django's per-site cache middleware work for me?

Question

I am using Django 1.3 beta 1 and set up memcached. I made changes to my settings.py per Django's instructions:

CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.memcached.PyLibMCCache',
        'LOCATION': '127.0.0.1:11211',
    }
}

MIDDLEWARE_CLASSES = (
    'django.middleware.cache.UpdateCacheMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.middleware.cache.FetchFromCacheMiddleware',
    #'debug_toolbar.middleware.DebugToolbarMiddleware',
)
CACHE_MIDDLEWARE_SECONDS = 100000
CACHE_MIDDLEWARE_KEY_PREFIX = 'site_cache'

This is the test view function I'm hitting:

def home(request):

    print 'uncached'

    # ...View's code...

I always get uncached printed on the development server's output and I always get hits to the database. Why? Am I missing something or just misunderstanding caching completely?

Edit #1:

Template fragment caching works perfectly fine. Am I just missing something? Please help.

Answer 1

It appears that you have everything set up correctly. The only possible caveat I can see in the documentation is the following:

The cache middleware caches every page that doesn't have GET or POST parameters.

Unfortunately, I'm assuming you already know this and it won't help you.
