When I load a page, is there a way to show an address in the browser naviagtion bar which is not the page address. Kind of like spoofing a page, but without using frames.

My site is currently using a forwarding script for our DNS, and it forwards to a location behind an IP address. I want to make it so that the original page address www.whatever.com (http://www.whatever.com) is still at the top, but frames can only be loaded when the page is executed, and at this time, it is located behind the IP address.

I want anything which would "change" the address in the address bar to its original.
