A subdomain is another web site with the same domain name "suffix". For example, if you have the registered domain, "yourdomain.com" and serve a web site on "www.yourdomain.com", ProWeb accounts can serve a different web site on "different.yourdomain.com" without any special configuration changes or fees.
We have a magic system setup which will automatically convert a sub-domain address like "something.yourname.com to a sub-directory address like http://www.yourname.com/something. You only need to request for this system to be setup once, and from then on
We can set it up so that either something.yourname.com will stay as something.yourname.com in the address bar, or that something.yourname.com will change to http://www.yourname.com/something.
Some users prefer one sort of subdomain rewrite, other users prefer the other sort.
When something.yourname.com stays like that in the address bar, it opens the folder /something. /something now becomes the "document root", and if you were to link to "../index.html", it could not open http://www.yourname.com/index.html. When somethingelse.yourname.com forwards to http://www.yourname.com/somethingelse, you can link to "../index.html" and it would open http://www.yourname.com/index.html.
