Thanks Bruno.

I'm so sorry for restating it again my situation before trying it; the
situation like this:

Right now, when you go to http://mycompany.com it goes to nowhere
since it doesn't resolve to any IP address.

I'm thinking, we can do it in the DNS that when someone trying to
access http://mycompany.com it should resolve to www host.

Thanks.
