I have a project on domain example.com all css files for this project are getting from cdn.example.com in this css files I used only relative paths e.g.
background:url(../../images/colorbox/loading.gif) no-repeat center center;
Due to this path for images should be cdn.example.com/../../images/....
But all images are loading from example.com/... not cdn. Is there any advices, For loading images from cdn?
