default pages in ASP.Net + not displaying page names in browser ...How?

Is it possible to not display a page name in the browser - i.e. not show
the ".aspx" extensions in the browser ?.

Typically, a link on an ASP.Net website would look something like this:
>
http://www.thewebsite.com/folder1/page.aspx
>
I want to drop the page name completely, so the above link would be
(instead) :
>
http://www.thewebsite.com/folder1/
>
For example, for PHP based websites, the default script launched (per
specified folder) is index.php - so one does not have to explicitly
specify the script being run as part of the url.

Is there a corollary in ASP.Net ?
