Title: Fix to enable external CSS from both Site Domain and CDN/X-Domain at the same time

When using the cross-domain setup for stylesheets hosted on a CDN, local stylesheet files (on the site domain) cannot be loaded. IE8 raises a "Permission denied" error. This fix prevents local stylesheets to be processed by the proxy.
