### Cache configuration options
> [!NOTE]
> If you are using Redis as cache, you need to set the policy to one of the variants of allkeys.
> If you don't do this, the cached data doesn't expire, and you will run out of memory.
> You can get more information on how to set the Redis policy in the Rails [documentation](https://guides.rubyonrails.org/caching_with_rails.html#activesupport-cache-rediscachestore).
* `rails_cache_store`: `memcache` for [memcached](https://www.memcached.org/), `redis` for [Redis cache](https://redis.io/), or `memory_store` (default: `file_store`)
* When using `memcached`, the following configuration option is relevant:
* `cache_memcache_server`: The memcache server host and IP (default: `nil`)
