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

Note: this only works with supporting cache stores, like the MemCacheStore
