The cache framework is split into a set of "backends" that provide different
methods of caching data. There's a simple single-process memory cache (mostly
useful as a fallback), a database-backed cache, and a memcached_ backend (by

Really, that's the entire API! There are very few restrictions on what you can
use the cache for; you can store any object in the cache that can be pickled
safely, although keys must be strings.
