 * The in-memory session store keeps every session into memory.
 *
 * This has a few major effects:
 *
 * 1. If the server restarts, all sessions are gone.
 * 2. This only ever works with one server. If you need to scale, you need
 *    a different store.
 * 3. It's also leaky in terms of memory. Many active sessions means higher
 *    memory usage.
 *
 * This session store is great for very small scales and testing. You can
 * easily get going with the memory store, and upgrade to a different one
 * when you need it.
