I have a website  www.website.com  that when entered like that it opens a deafult page.   

I have the code

string Linkname;
            if (Request.PathInfo.Length != 0)
                Linkname= Request.PathInfo.Substring(1);
            else
                Linkname="xyz";

and then I load the page.  the issue is when I type www.websitet.com/xyz I get a 404 error.  but if I type www/websitet.com/DocumentList.aspx/xyz it works fine. 

How do you set up iis 7 in order so that instead of trying to go to the directory xyz it will go to my default page (documentlist.aspx) and look at the Pathinfo.

Thanks
