More documentation on this is needed... what works, what doesn't, what will.
W3-Total-Cache added the CDN feature to work with Amazon's "existing CDN", yet, it's Amazon who "doesn't support all of the headers in the proper way"?
I will have to shoot Amazon a note and request they make changes to meet W3's headers then.
Amazon is the existing service so to me it would be more about clearly identifying what headers work or dont work and also trying to make things work from the W3 end.
But I probably have things the wrong way around.
Thanks anyway. Enabled the "browser cache" and enabled "Set expires header" for media files it works on "our" wp files on server but NOT on the uploaded amazon bucket files.
Our server returns:
...while it's a noticeable performance hit when Amazon CDN returns:
"X-Cache: Miss from cloudfront"
