+# Caching
+
+Out of the box, Joodle provides support for [RFC 7234](https://httpwg.org/specs/rfc7234.html) compliant HTTP caching. Fresh cache entries are served directly from the cache, and stale entries are revalidated with `If-None-Match`/`If-Modified-Since` headers.
+
+## Supported Cache Stores
+
+Joodle uses Keyv internally to support a wide range of storage adapters, including anything that implements the native JavaScript [Map API](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map).
+
+This means that you can use an in-memory store:
+
+```js
+...
+const inMemoryStore = new Map();
+
+const joodle = new Joodle(
+  ...,
+  {
+    ...,
+    cache: inMemoryStore
+  }
+);
+```
+
+Or you can use a more persistent store such as Redis (using [@keyv/redis](https://www.npmjs.com/package/@keyv/redis)):
+
+```bash
+$ npm install @keyv/redis
+```
+
+```js
+...
+const KeyvRedis = require("@keyv/redis");
+
+const redis = new KeyvRedis("redis://user:pass@localhost:6379");
+
+const joodle = new Joodle({
+  ...,
+  {
+    ...,
+    cache: redis
+  }
+})
+```

 The `rejectInvalidSSL` option indicates whether the client should reject invalid SSL certificates or not. By default, the client will reject invalid SSL certificates.
 
+The `cache` option allows you to enable HTTP response caching. By default, the client will not cache any responses. See the [Caching](/guide/caching.html) section for more information.
+
 ::: danger
 You should only set the `rejectInvalidSSL` option to `true` when connecting to local Moodle instances (`baseURL: "https://localhost"`). There are severe security implications when accepting invalid SSL certificates from remote Moodle sites.
