I've enabled W3 Total Cache for my site with AWS CDN. I'm minifying several CSS files and noticed that the CSS properties with url information for loading images are not rewritten to fetch the images from the CDN.
Some of my CSS properties also included relative urls. Combining those CSS files broke the reference because the result minified CSS is not at the same path depth. I had to take them out. The CDN serves them so not a great loss.
Any suggestion? Am I missing a setting? (I checked the code and there appears to be a "postprocessing" step that can be applied to the minify... Perhaps that can be use to at least fix the embedded absolute references.)
