This is an addition to Django's cache_page decorator.
I wanted to cache pages for anonymous users but not cache the same page for logged in users. There's middleware to do this at a site-wide level, and it also gives you the ability to partition anonymous users, but then you have to tell Django which pages not to cache with @never_cache.

from django.middleware.cache import CacheMiddleware
# Note: The standard Django decorator cache_page doesn't give you the anon-nonanon flexibility,
# and the standard Django 'full-site' cache middleware forces you to cache all pages.
def cache_page_anonymous(*args, **kwargs):
"""
Decorator to cache Django views only for anonymous users.
Use just like the decorator cache_page:
@cache_page_anonymous(60 * 30) # cache for 30 mins
def your_view_here(request):

key_prefix = kwargs.pop('key_prefix', None)
return decorator_from_middleware_with_args(CacheMiddleware)(cache_timeout=args[0],
key_prefix=key_prefix,
cache_anonymous_only=True)
# Usage:
#
# from your_utils_package_here import cache_page_anonymous

# @cache_page_anonymous(30) # cache for 30 secs
# def my_view(request):

Comments
Django also has CACHE_MIDDLEWARE_ANONYMOUS_ONLY setting, which allows to enable per-site cache for anonymous users on page without GET or POST request.
