Are cache tags supported (and their invalidation) with App Platform and the Cloudflare CDN? I’d like to make sure my requests have proper Cache-Tag headers. The problem is that invalidation with Cloudflare is an API based process.
If the Cache-Tags header isn’t available, what is a good way to handle cached responses on App Platform without setting a low Cache-Control header.

App Platform doesn’t support Cache-Tag headers at this time, however, you can make use of Cache-Control headers per Cloudflare’s guidelines: https://support.cloudflare.com/hc/en-us/articles/115003206852-Understanding-Origin-Cache-Control
For Static Site components, we set a Cache-Control header automatically and explicitly purge the CDN cache on each app deployment. I hope that helps!
Is there a way to increase max-age? 10 seconds for hashed JS file names seems way too low. Perhaps for .html extensions it makes sense but for CSS/JS etc. it would make sense to have a higher number if the asset names are hashed.
Hi there,
Quick update here in case that it helps, App Platform edge controls are now generally available, giving you more control over your app’s CDN and security behavior. The new features include email obfuscation, enhanced threat control to help mitigate layer 7 DDoS attacks, and CDN cache controls for fine-tuning content delivery.
You can find full configuration details here: https://docs.digitalocean.com/products/app-platform/how-to/configure-edge-settings/
