-Static is a flexible, light and simple runtime dedicated to static sites generators (SSG), designed for minimum configuration effort with Auto-build feature. Pico instances are available, it allows users to put services in front of it, such as [Redirection.io](/doc/reference/reference-environment-variables/#use-redirectionio-as-a-proxy) or [Varnish](/doc/administrate/cache/).

+## Overview
+
+[Varnish](https://www.varnish-cache.org/) is an HTTP proxy-cache that sits as a reverse proxy between your application and the client. It caches responses according to rules you define, reducing load on your application. Clever Cloud provides **Varnish {{< runtime_version varnish >}} and varnish-modules {{< runtime_version varnish-modules >}}**.
+
+> [!NOTE] Supported runtimes
+> Varnish is available on all runtimes that support [Request Flow](/doc/develop/request-flow/): **.NET**, **Elixir**, **FrankenPHP**, **Go**, **Haskell**, **Java**, **Linux**, **Node.js & Bun**, **PHP with Apache**, **Rust**, **Static**, and **V (Vlang)**
+
+## Enable Varnish for your application
+
+Create a `varnish.vcl` file in the `clevercloud/` folder at the root of your application. You can also set the `CC_VARNISH_FILE` environment variable to a custom path within your application root, written as an absolute path starting at `/` (for example `CC_VARNISH_FILE=/config/varnish.vcl`). If the file does not exist, deployment fails.
+
+This file describes how Varnish caches your application's responses and when it returns a cached resource. To learn how to write your `varnish.vcl` file, refer to the [Varnish documentation](https://varnish-cache.org/docs/8.0/index.html).
+
+The `vcl 4.1;` declaration and backend section are not necessary as they are already handled by Clever Cloud. If your `varnish.vcl` file is stored on an FS Bucket, redeploy the application for changes to take effect.
+
+## Listen on the right port
+
+Varnish is managed through [Request Flow](/doc/develop/request-flow/). Once Varnish is enabled, your application must listen on port **9000** instead of **8080**. Request Flow places Varnish (and any other configured middleware) between the public port (`8080`) and your application. In runtimes where Clever Cloud manages the port configuration (FrankenPHP, Java, PHP, Static), this is handled transparently.
+
+## Configure the cache size
+
+Set the `CC_VARNISH_STORAGE_SIZE` environment variable to configure the Varnish cache size (default: `1G`).
+
+```bash
+CC_VARNISH_STORAGE_SIZE=2G
+```
+
+## Varnish migration
+
+If you have a configuration for an older version of Varnish, read:
+
+- [Upgrading to Varnish 7.0](https://varnish-cache.org/docs/7.0/whats-new/upgrading-7.0.html) guide
+- [Upgrading to Varnish 8.0](https://varnish-cache.org/docs/8.0/whats-new/upgrading-8.0.html) guide
+
+## Example files
+
+Clever Cloud provides [example Varnish configuration files](https://github.com/CleverCloud/varnish-examples). Download the one that fits your needs, rename it to `varnish.vcl` and place it in the `clevercloud/` folder at the root of your application.
+
+## Varnish with a monorepo
+
+If you use a monorepo, you may want to use Varnish for only some of its applications. Use `CC_VARNISH_FILE` to point to a specific configuration file.
+
+A `clevercloud/varnish.vcl` file at the root of your monorepo activates Varnish for all applications. To limit Varnish to specific applications, place the file elsewhere and create a symlink during deployment only for the applications that need it:
+
+```bash
+CC_PRE_BUILD_HOOK="mkdir $APP_HOME/clevercloud; ln -s $APP_HOME/path/to/your/file/varnish.vcl $APP_HOME/clevercloud/varnish.vcl"
+```
+
+Applications without this hook or without `CC_VARNISH_FILE` set will not use Varnish.
