Help with subdomain

[inetiatic]

First off, i use Godaddy as my domain and hosting provider.
example..
i have ample.com
and i want the main URL to be ex.ample.com (like that of del.icio.us and others)
How can i use a sub domain to the main url/domain of the website. eg. if i go to ample.com it directs to ex.ample.com.

Either forward it in cPanel under subdomains or use meta refresh in a index.html file in your subdomains root folder:

<meta http-equiv="refresh" content="0;url=http://ample.com" />

So i should create a directory for my sub domain? it currently points to my root folder, just like that of the main address.

Use a 301 redirect in the .htaccess file :)
