We are experiencing an issue with browser caching where we have set the following:
Cache App -> Browser cache TTL set to 3 hours as we have multiple sub-domains that will fall under this TTL bracket.
Recently we have set-up CF workers and these are running on a separate subdomain from www and the Cache-Control is always being set to 10800 (3 hours) when we have set specific page rule for this sub-domain to be a max of 30 mins.
Did we get the logic wrong as to how Cloudflare works?
I have double-checked that the hostname is correct in the page rule and it is definitely correct e.g.
Any help would be appreciated, thank you.
