get a domain address with asp

how do I get the domain of an address to the asp?

Suppose we have the following addresses:

example.com

开发者_如何学Cexample.com/my

example.com/news/nacional

example.com/news/naciona/nada-como-um-dia.html

I'd like to get just the domain, in this case o. ..

"example.com"

I take the field as an address to the asp?

Thanks!
