Cache-Control Caddy Reverse Proxy and Ghost caching settings

Developer help Installation

Hi,

I can see Cache-Control by Caddy Reverse-Proxy and those set by Ghost. if i set to “no cache” some parts of website, I still get cache max age settings from Ghost. Should I disable Ghost’s cache settings or perhaps disable caddy caching?

This what I got for the image file. As you can see Cache-Control is doubled.

HTTP/2 200

cache-control: public, max-age=604800, must-revalidate #### That's Caddy Proxy setting
cache-control: public, max-age=31536000 ##### It was added by Ghost CMS, I think.

What does your Caddyfile look like? Usually, there’s no need of any custom cache control overrides on reverse proxy layer.

Indeed, I am not sure Ghost caching is good enough, if it does then maybe I do not need proxy caching.
