Cloudflare CDN expiry in Drupal


I am developing a Drupal site, and we are in the process of moving our DNS to Cloudflare. We have of course been tempted by several things, one of which is the CDN that comes as part of it. Sadly though, all Drupal related documentation points to a module which uses an old version of Cloudflare, so wondered if there is another recommended approach for expiring/purging from a Drupal website that anyone can recommend to me.

Alternatively, is there a standard CMS solution that we could look at implementing in Drupal maybe (using headers)?
