here is my problem : CORS are set as supposed to be on the S3 :
<CORSConfiguration>
<CORSRule>
<AllowedOrigin>*</AllowedOrigin>
<AllowedMethod>GET</AllowedMethod>
</CORSRule>
</CORSConfiguration>
when I try to fetch a file (using jQuery with option CrossDomain = true)
from A.example.com -> B.example.com/file.js (works with correct Headers) When I try the same request from another domain : C.dev.example.com -> B.example.com/file.js // (it fails)
However for the second example when I look at the network logs in chrome my first request OPTIONS:
it has the correct CORS response headers :
access-control-allow-headers: access-control-allow-headers
access-control-allow-methods: GET
access-control-allow-origin: *
access-control-max-age: 3000
content-length: 0

However the GET Request (right after the OPTIONS) :

My TTL on the Cloudfront is 5 seconds (It has to be aggressive for my use case) I'm using the h2 protocol instead of the http/1.1
