does askbot namespace its mecached keys?

Fedora infrastructure team wants to know this. They recommend that askbot namespace all its keys to avoid two applications overwriting each others cached values since memcached doesn't have a permission system.

In version 1.3 they've slightly changed the way the cache settings are structured:

The old way te set it up to version 1.2 - by using CACHE_MIDDLEWARE_KEY_PREFIX setting, in 1.3 - the setting was changed to a member of cache key dictionary called KEY_PREFIX.

Django 1.3 and above supports use of multiple cache stores, take a look at the doc page.
