Hide page url without url rewriting

[aspfun]

I created a asp.net program as http://mycompany.com/
I want whenever user clicks any link, such as

http://mycompany.com/order.aspx

http://mycompany.com/bill.aspx

http://mycompany.com/report.aspx


it should come
http://mycompany.com/

means page name should not show to user.

I Google it but I don't like url rewriting.

Is there a simple way or tool can do it?

You can use Javascript and window.location.hash problem is i am not sure if it will work on IE's.

You could put the entire site in a div and load the content of that div when the user navigates, but this breaks the backbutton
