Question
Cloudflare cache invalidation on App Platform

Asked by Matt Glaman
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.
