defmodule PowPersistentSession.Plug.Base do

  @moduledoc """

  Base module for setting up persistent session plugs.



  See `PowPersistentSession.Plug.Cookie` for an implementation example.



  ## Configuration options



    * `:persistent_session_store` - the persistent session store. This value

      defaults to `{PersistentSessionCache, backend: EtsCache}`. The `EtsCache`

      backend store can be changed with the `:cache_store_backend` option.



    * `:cache_store_backend` - the backend cache store. This value defaults to

      `EtsCache`.
