CloudFront with long shared cache and short browser cache -


i'm using cloudfront in front of s3 serve images. origin (s3) sets following cache headers: cachecontrol: max-age=86400,s-maxage=31536000. expectation here cloudfront cache image 1 year, , browser cache day. after that, should hit cloudfront again , cached image, , cache "new" item rest of day.

the issue i'm encountering date header cloudfront when cached in cdn. so, after 1 day of being cached in cdn, browser no longer caches images, , hits cloudfront every time. @ point age of item has exceeded max-age value. until cloudfront item invalidated or expired, browser never retrieves item caches.

is possible set such browser caches each subsequent day, cloudfront ttl can set long year?
