Great plugin, one small issue I have run into. I am using Minify CSS for a CDN, my cdn address is like this:
This works ok for most things (replacing the asset calls to cdn.example.com/beta/wp-content/[etc..], however, as W3TC rewrites the CSS to use absolute paths ('/wp-content/themes/mytheme/my-image.png') this then doesn't work when the CSS is moved to the CDN at cdn.example.com/beta/.
Should this be possible? Or am I asking something that is not supported by W3TC?
