Has anyone come across this issue where Amazon Cloudfront seems to refuse to cache a certain small number of static objects?
I've tried invaliding the cache (root path) several times to no avail.
I had a look at the file permissions of the objects in question, and they seemed all ok.
I've also gone into the Amazon Console and there are no errors logged.
You can see more details of this here :

I recently upgraded this test site to PW 3.062 from PW 2.8.x and noticed this was happening. I'm also running the latest version of Procache on this site.
