class ActionDispatch::Session::CacheStore

Parent:: ActionDispatch::Session::AbstractStore

A session store that uses an ActiveSupport::Cache::Store to store the sessions. This store is most useful if you don't store critical data in your sessions and you don't need them to live for extended periods of time.

Options

cache - The cache to use. If it is not specified, Rails.cache will be used.
expire_after - The length of time a session will be stored before automatically expiring. By default, the :expires_in option of the cache is used.
