Warning The default server-side session storage, MemoryStore, is purposely not designed for a production environment. It will leak memory under most conditions, does not scale past a single process, and is meant for debugging and developing.
As we expect many hundreds, or even thousands, of requests, this should be changed to something else than memory.
