Always have the location/address bar point to my homepage?

Okay groovers, How can I maintain a certain URL in the various browser's location bars at *all* times. I.e., no matter if the client is at my homepage (./homepage.html) or 3 levels deep in (./dir/subdir/subsubdir/lowerpage.html) I always want the url info in the browser (Location bar in NS and Address bar in IE) to ALWAYS say http://www.mysite.com. Why? 1) To hide any GET query_strings on the line (although I post them, I'm still intrigued) 2) To _not_ use frames. 2nd Q: If I can achieve this would bookmarking my page put lowerpage.html's title in the bookmark, but set the URL to mysite.com? Thanx team! Matty.
