My result says that I have an "F" for cached static content

[bundaumamtom1989]

The report say that all the images that I serve from CloudFront - S3 has no max-age or expires

For example this one:
FAILED - (No max-age or expires) - http://i1.static.truyentranhgay.com/mon-...42c93d.png

And this is what I came up when using Chrome

Code:

While I passed Google Page Speed and YSlow on this same item. What could be the reason?

If you're getting a 304, you aren't setting expires headers on the object so the browser can cache it. The max-age=0 cache-control is also a give-away.

I don't know why page speed gave you a pass for that but it shouldn't.

I'm having this same issue. Did you ever get this resolved?

[pmeenan]

Do you have a link to a test result and what is "this"? Getting proper caching headers on S3?
