How can I fix "(No max-age or expires)" with Amazon CloudFront?

[fonnet]

Hi,

I had the same "No max-age or expires" results for my images that are stored on s3 and served by cloudfront. I've specified in s3 the meta tag cache-control. I've tried max-age=2592000 and public,max-age=2592000. It lasted all day long.

I just reran the test in order to put a link in this thread and... it's ok now! I'm happy but has anyone encounter the same issue with cloudfront or know what it could mean ?

Best regards,
Fonnet.
