To prefetch content from origins to CDN servers:

Management console

CLI

API

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

If you do not have the Yandex Cloud CLI installed yet, install and initialize it.

By default, the CLI uses the folder specified when creating the profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also set a different folder for any specific command using the --folder-name or --folder-id parameter.

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

Get a list of all resources in the default folder:

yc cdn resource list --format yaml

Specify the paths to the files you want to prefetch as a comma-separated list with no spaces:
```
yc cdn cache prefetch --resource-id <resource_ID> \
  --path <file_paths>
```
For more information about the yc cdn cache prefetch command, see the CLI reference.

Use the prefetch REST API method for the Cache resource or the CacheService/Prefetch gRPC API call.
