Expiring MemoryStore is a modification to the default Rails MemoryStore which adds the :expires_in functionality that is so useful with Memcache.
Although this increases the memory overhead slightly,
it ensures that caches can be expired easily, without restarting your webserver.
Just add;
config.cache_store = :expiring_memory_store
to your environment.rb.
>> Rails.cache.write('are you there?', :im_still_here, :expires_in => 30)
=> :im_still_here
>>'are you there?')
=> :im_still_here
wait 30 seconds
>>'are you there?')
=> nil
