One "site" with 3 urls's WP-multi with some plugin..

Hi.

I want to use eather the Domain Mapping or Multi Domain plugins for one client.

If you see http://www.calpro.no/ and click on menu Products –> Phical Test, you will se that the url changes.

That URL is now a static page, “blended” in with the site with same menus and so on, so it is only “1 site”..

I want to use WP multisite with some plugin to achieve the same result.

Can anyone point me in the right direction?

Regards Eddie
