+## Headers and redirects
+
+Custom [headers](/workers/static-assets/headers/) and [redirects](/workers/static-assets/redirects/) are supported at build, preview and deploy time by adding `_headers` and `_redirects` files to your [`public` directory](https://vite.dev/guide/assets#the-public-directory).
+The paths in these files should reflect the structure of your client build output.
+For example, generated assets are typically located in an [assets subdirectory](https://vite.dev/config/build-options#build-assetsdir).
