All Implemented Interfaces:

ImportAware, ResourcePostProcessor, ResourcePreProcessor

public class DuplicatesAwareCssDataUriPreProcessor

Similar to CssDataUriPreProcessor which instead of replacing a url blindly with dataUri, is is smart enough to detect duplicated image url and avoid replacing it with dataUri.
