| To use the two-layer cache: | |
| * Run memcached on each Django webserver | |
| * Add "LOCAL_CACHE_ADDR = ('127.0.0.1:11211',)" to settings.py | |
| * Replace "from django.core.cache import cache" with "from dualcache import cache" everywhere | |
| you want to use the two-layer cache. It can be freely mix and matched with Django's default caching. |

Github gists don't support Pull Requests or any notifications, which made it impossible for me to maintain this (surprisingly popular) gist with fixes, respond to comments and so on. In the interest of maintaining the quality of this resource for others, I've moved it to a proper repo. Cheers!
