That is a bad idea if for nothing else then that it prevents users from being able to bookmark your site.
There are two ways to do this, however, if you are intent on this direction (and I really do suggest that you turn back now before it is too late). You can load everything in an iframe:
<!-- your site might look like this then -->
<html>
<body><iframe src="http://path.to.your.real.site" />
</html>
And the src property would be directing to some other URL which actually has all of the dynamic URL's.
Your other option is AJAX. That is really too long and complicated for an example though.
