Setting ttl
Use the expires_in option to set a TTL for the cached item.
Rails.cache.write("top_items", :expires_in => 5.minutes)
You can use this with the fetch method as well:
Rails.cache.fetch("top_items", :expires_in => 5.minutes) do # some very expensive calculations end
Note: this only works with supporting cache stores, like the MemCacheStore
