I have a static site running on https://supera.netlify.app/. Some images are coming from a CMS dynamically. Instead of directly getting the images from the CMS, I proxy them through Netlify with the following redirect:
/assets/* https://content.pinelab.studio/assets/:splat 200
This is working fine, but it seems the images are not cached, even though the cache header is set to 30 days:
cache-control: public, max-age=2592000
I also see
server: Netlify in the response headers.
This page has an example image coming from the CMS: Super A - Super A
The CMS runs on Google Cloud Run, which sometimes takes some time to spin up, resulting in a ~2 second delay before images show up.
I hoped proxying through Netlify would cache all the images. Is this a wrong assumption, or did I misconfigure something?
Thanks in advance!
