 Please make sure that "/" is writable by the web-server.
 ```
 
 With {{site.data.var.ece}}, you can only write to specific directories, such as `var`, `pub/media`, `pub/static`, or `app/etc`. When you generate the `sitemap.xml` file using the Admin panel, you must specify the `/media/` path.

Generate the `sitemap.xml` file in the Magento Admin panel as described above, then create a custom Fastly VCL snippet to manage the redirect. See [Custom Fastly VCL snippets]({{ page.baseurl }}/cloud/cdn/cloud-vcl-custom-snippets.html).
