"No max-age or expires" with Amazon CF, advise

Hi and thanks for the great help and tools

These are my results: http://www.webpagetest.org/result/160214_PY_VQD/1/performance_optimization/

I’m using Amazon CF CDN which results in this issue. I’ve attached my CF Behavior settings - is there anything wrong there?
Should I invalidate the cache in order for it to take the new settings or something?


please help?

From the looks of the cloudfront docs, those settings just control the time that objects live in their edge cache but the origin still needs to specify explicit expires or cache-control headers: http://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/Expiration.html#ExpirationDownloadDist
