Question
Cloudflare cache invalidation on App Platform
- Posted December 22, 2020
- DigitalOcean App PlatformCDN
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-Tagheaders at this time, however, you can make use ofCache-Controlheaders per Cloudflare’s guidelines: https://support.cloudflare.com/hc/en-us/articles/115003206852-Understanding-Origin-Cache-ControlFor Static Site components, we set a
Cache-Controlheader 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.
