 Adds experimental session support
+
+Sessions are used to store user state between requests for server-rendered pages, such as login status, shopping cart contents, or other user-specific data.
+
+```astro
+---
+export const prerender = false; // Not needed in 'server' mode
+const cart = await Astro.session.get('cart');
+---
+
+<a href="/checkout">🛒 {cart?.length ?? 0} items</a>
+```
+
+Sessions are available in on-demand rendered/SSR pages, API endpoints, actions and middleware. To enable session support you must configure a storage driver. If you are using the Node.js adapter, you can use the `fs` driver to store session data on the filesystem:
+
+```js
+// astro.config.mjs
+{
+  adapter: node({ mode: 'standalone' }),
+  experimental: {
+    session: {
+      // Required: the name of the Unstorage driver
+      driver: "fs",
+    },
+  },
+}
+```
+If you are deploying to a serverless environment there are other drivers that you can use, such as `redis` or `netlifyBlobs` or `cloudflareKV`.
+
+For full details, see [the docs for experimental session support](https://docs.astro.build/en/reference/experimental-flags/sessions/).
