URL rewriter

Hi

I am using url rewriter from http://urlrewriter.net/

I have 2 pages default.aspx and show.aspx on root.

I have 3 links on default.aspx and they are redirecting to show.aspx page. Href set to them is as below:
1.href="2006/08/16"
2.href="2006/08"
3.href="2006"

URLs on show.aspx should look like:

1.http://localhost/UrlRewrite/2006/08/16  : Should show data of year 2006 , month 08 , date 16 
2.http://localhost/UrlRewrite/2006/08      :  Should show  data of year 2006 , month 08
3.http://localhost/UrlRewrite/2006           :  Should show data of year 2006

I am using following 3 rules in web.config :

<rewrite url="(\d{4})/(\d{2})/(\d{2})" to="~/show.aspx?Year=$1&amp;Month=$2&amp;Day=$3"/ ...
