Hello, I am a user of cloudflare free for a few months, when reviewing my Apache server logs, I see that some images are still served by my server, why is that happening? Shouldn’t they be sent from cloudflare?
basically CF will cache based on your cache control headers but unmentioned exception is if the cached asset/file isn’t frequenty used, it will be purged i.e. you cache .png image for 1 yr but the .png image hasn’t been requested in several months, the CF will in all likely hood purge it from their cache. This is what I have been told.
See https://support.cloudflare.com/hc/en-us/articles/115003206852 as well. Basically, as long as the assets/files are frequently requested, you can be sure they’re served from per data center cache for length of your cache control specifications. Ask yourself, would you care if a infrequently used file is purged earlier from cache if it has only ever been requested a few times over time ?
thanks for your answer, but assuming I have all the settings ok, why do I see that for example google bot still downloads images from my server and not from cloudflare?
