Max Age for Edge Cache TTL

1

I want to make sure

Access-Control-Allow-Credentials:
true
Access-Control-Allow-Origin:
https://example.com
Age:
1896
Alt-Svc:
h3=“:443”; ma=86400
Cache-Control:
max-age=14400
Cf-Cache-Status:
HIT

I know that Cache-Control: max-age=14400 refers to time the file will be cached for in user’s browser (this is what I set in Cloudflare) Does Alt-Svc: h3=“:443”; ma=86400 refers to time the file will be cached for in Edge Cache TTL? 86400 - 24 hours. Is the the max age the fly app is sending? If so, is there any way to increase this number through Fly or the only way is to create page rules via Cloudflare

Thank you in advance for any response

Fly.io doesn’t set any Cache-Control headers. You’d have to adjust those settings in Cloudflare, as you mentioned. Here are more details on Cloudflare’s default caching behavior: Default Cache Behavior · Cloudflare Cache (CDN) docs
