How to get Domain to point to subdirectory?

Hi All,

I have an application that will have several domains pointing to
different paths within my application.

For example:
www.johndoe.com should point to:
http://www.peoplepages.com/people/1

or
www.sallyjohnson.com should point to:
http://www.peoplepages.com/people/5

Is there a way to get the domain to point to these subdirectories… but
NOT show the subdirectory?

(I don’t want the browser to show the path, I just want the browser to
show www.johndoe.com)

Thanks!
Dustin
