You don't really mask the URL - What you can do is use is something called a MODrewrite module if you are on an apache server.

never heard of this, sounds dangerous though and could be used for stealing peoples information?

Here's probably a more important question - do you own both abc.com and xyz.com?

hmm, you can try ask a coder

Do you mean cloak your URL?
Well, if you have a site you could do it with your site folder....

for more information about it, you could refer to this man post.
