My images were being cached beautifully up until a month ago and then suddenly they were not anymore. My server is sending a 1 month cache-control header but CF still keeps saying bypass or miss for every single static JPG or PNG image.
That’s the issue when you have a load balancer behind Cloudflare and you want to to enable sticky sessions.
Can load balancer selectively add session cookies to only HTML pages? If not, you need to create a Cache Everything page rule just to force caching the static content, or having a separate server without the load balancer just to serve static content.
