This method only returns a cache
manager object of sorts, to see what you can do with it, see ActiveSupport::Cache::Store.
Most common use case is probably:
Rails.cache.fetch "some key" do
compute some value
This computes some value and caches it. Subsequent invocations will return
cached value (as long as it is still cached).
