title: Wrong relative path in css on cdn
body: <p>I have a project on domain <strong>example.com</strong> all css files for this project are getting from <strong>cdn.example.com</strong> in this css files I used only relative paths e.g.</p>
  
  <pre><code>  background:url(../../images/colorbox/loading.gif) no-repeat center center;
  </code></pre>
  
  <p>Due to <a href="https://stackoverflow.com/questions/2718532/is-a-relative-path-in-a-css-file-relative-to-the-css-file">this</a> path for images should be <strong>cdn.example.com/../../images/....</strong></p>
  
  <p>But all images are loading from <strong>example.com/...</strong> not <strong>cdn</strong>. Is there any advices, For loading images from cdn?</p>
