This is an (overly simple) example of how to manually delete something from the cache.

Usage is simply delete_url_cache('/some_view/')

This most likely doesn't work when using Vary headers but does seem to work fine for the most general case of simply needing to programmatically flush the cache after certain actions.

from django.conf import settings
from django.core.cache import cache
from django.utils.encoding import iri_to_uri

def delete_url_cache(url):
    """ simple method to delete the cache for a particular URL """
    key_prefix = settings.CACHE_MIDDLEWARE_KEY_PREFIX
    cache_key = 'views.decorators.cache.cache_header.%s.%s' % (key_prefix,
                                                               iri_to_uri(url))
    cache.delete(cache_key)
