This takes advantage of a recently added feature to django, being able to give it real functions as the view instead of having it be a string that is has to look up itself.

It takes advantage of how decorators work and how cache_control works, normally you'd do something like this:

@cache_control(private=True, public=False)
def view_stuff(request):
    # ...
    return response

Which is equal to doing view_stuff = cache_control(private=True, public=False)(view_stuff) after definition. cache_control is a function factory, more or less, which we use to our advantage.

from django.views.decorators.cache import cache_control
from someproj.someapp.views import foo_view

# ...

open_cache = cache_control(private=True, public=True)

urlpatterns = patterns('',
    (r'^foo/$', open_cache(foo_view)),
    # ...
)
