To prefetch content from origins to CDN servers:

Management console

CLI

API

In the management console, select the folder where your resource is located.
Select Cloud CDN.
Click the resource name.
Go to the Content tab.
In the top-right corner, click and choose Preload content.
Enter the file names in the File path field.
Click Preload content.

If you do not have the Yandex Cloud command line interface yet, install and initialize it.

The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name or --folder-id parameter.

View the description of the CLI update resource command:
```
yc cdn resource update --help
```

Get a list of all resources in the default folder:

yc cdn resource list --format yaml

```
