Queue non-Drupal files and front-end

I currently have an authenticated Drupal rest API, FILES on S3, and front-end WWW web app. When the back-end Drupal CMS content updates I need the FILES and WWW to be purged (which are both behind CloudFront). I do not need API or CMS to be purged.

When I run the spider command, it fails with a "403 Forbidden" since the CMS and API are authenticated. How do I get the spider/queuer to queue the non-Drupal FILES and WWW?
