 ## Description
 Mnemosyne is placed between your load balancer (ex: nginx) and your server applications that needs their requests to be cached. It will optimize the resources by caching responses and adding caching headers that will ask clients to re-use the cache locally. The cache will be expired based on activity and from manual invalidation.
