Let's say I have a domain a.com and a subdomain a.a.com
The folder of the subdomain is inside the main domain's folder, so accessing a.com/a/ is the same as accessing a.a.com.
If an image in index.php of the subdomain has url(/a/a.png) instead of url(a/a.png), when I load the subdomain a.a.com,
will there be any chance that I would download the image from a.com/a/a.png instead of a.a.com/a/a.png and result in an error?
