This feels like a very dumb question that should be obvious to me. 😉
If we have our site www.example.com but we’re pulling our CSS files from a cdn domain www.examplecdn.com if we have this in said css file…
.sample {background url('/images/myimage.gif')}
…which server will the browser request the images from? Is it consistent from browser to browser?
The URL is related to where the CSS is stored. So in this case the remote server would be the one asked for the image.
