301 Redirect- How to cannibalize homepage for windows server/asp?

How do I cannibalize a non www version to the www version of the site...I tried using this:

Code:

http://sitename.com: <%@ Language=VBScript %>
<%
Response.Status=”301 Moved Permanently”
Response.AddHeader “Location”, http://www.sitename.com
%>

try
# force www
RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]
