`POST /cdn/resources/{resource_id}/prefetch`

Pre-populate files to a CDN cache before users requests. Prefetch is recommended only for files that **more than 200 MB** and **less than 5 GB**.

You can make one prefetch request for a CDN resource per minute. One request for prefetch may content only up to 100 paths to files.
