I'd guess it's DFS: http://damnfineshave.com

correct.

Damn... sorry, I just realized that this was already posted. I assumed it is a different website because of the "on my new website" part.

Your avatars are sending correct response headers, there is nothing to worry about.

Chrome Dev tools confirms this:



As expected, Firefox also respects the cache header.

PS: If you decide to test it yourself make sure to have "Disable cache" unticked. Dev Tools will disable cache by default.

interesting. why does gtmetrix not think the same?

Gtmetrix isn't exactly the most accurate test. Try http://www.webpagetest.org

looks like a lot of the google stuff is failing to be cached (google ads, google fonts, etc.). the avatars are getting dined for image compression, but that's probably to be expected.

Well there isn't any way to cache Google ads, I don't know about google fonts but considering how fast Google's CDN is I wouldn't worry about it. There isn't any reason to use an external tool, I find them unreliable for performance testing because they won't account for their own server load. I am not sure why GTmetrix is not detecting the cache headers but they are there, no need to worry about query strings.
