Constant url as address without the use of a frameset

Hi, I dont use frames and nor do I wish to use them. However there is something I have been aiming to do and countless times been asked, is whether or not you can keep a remaining url, without displaying its extensions.

For example if we were on the benefits.html or asp page, we would see the following in the address bar.

What I am after without using frames is for a constant url shown like below:

no matter what page you are on.

I am not sure if this is possible but if anyone has a clue as to how please let me know :slight_smile: and thanks.
