Today, we're excited to welcome MemCachier into the add-on catalog. MemCachier is a hosted Memcached service.
You should add MemCachier to your AppHarbor-hosted app to cache frequently used data and speed up your application. We've written a short guide on how to get started with Memcachier. We're working with the MemCachier guys to support easy configuration of their add-on for more advanced use cases such as using Memcached as a session state backing store.
