how to hide url path in ASP.NET

Hi I am using ASP.NET 3.5 with language VB. I want that the user cannot see to which page they are redirected to.. For E.g : if page is-- http://www.inetpub/user/login.aspx the browser shud display only
http://www.inetpub/user/ hiding the .aspx extension...& moreover even if user navigates to other page(s)
only the link http://www.inetpub/user/ should be displayed.


Is it possible?
