All of my subdomains are in my public html folder which means that anytime I upload a doc to the server in order for it to work the url must contain the primary or root domain instead of the sub domain. For example if the doc was bestdocs.pdf and the subdomain was www.subdomain.com instead of typing www.subdomain.com/bestdocs.pdf, I would have to type www.rootdomain.com/bestdocs.pdf. What do I need to do so that sub domains are entities of themselves or can I even do this?
