Uh-oh. Because the files have the same names, the CloudFront edge servers won’t update from the central asset server to use the latest image, and your users will continue to see the stale, old image.

There are a lot of CDNs out there, but I’ve decided to use Amazon’s CloudFront because it’s relatively cheap and easy to set up (not to mention it integrates seamlessly with S3).

In order to compress JavaScript and CSS files in my applications, I use Scott Becker’s AssetPackager plugin.
