Assigning Domain To Virtual Dir

as per the article given i tried to change the name frm locahost to abc.com
and in my browser i keyed in http://abc.go.com/
but its not displaying my page

You misunderstand how domains work. You're not going to get abc.com, because it is already taken by another company. I am not sure how you attempted to change localhost to abc.com, but domains aren't obtained for free.

lol you can't change that into something like abc.com since you are the localhost and the thing is abc.com was already taken by someone, maybe you must buy a domain name and update your nameservers

okas per u r suggestion i changed it to mywebstill the same page cannot be displayed
