currently my URL www.domain.com/ is index with google but the following pages also exist pointing to the same content

• www.domain.com/home.aspx
• www.domain.com/default.aspx

I have been informed that this will hurt our SEO.  I have managed to do a rewrite rule to forward home.asp to the root domain but when i try to do the same for default.aspx it causes and infinate loop.  the code i used is

      <add name="domainRewrite"
                virtualUrl="http://domain.com/home.aspx"
                rewriteUrlParameter="ExcludeFromClientQueryString"
                destinationUrl="http://domain.com/"
                redirect="Domain"
                redirectMode="Permanent"
                ignoreCase="true" />

am i able to setup redirects that point people to the root domain when they type in /default.aspx?  I am running Windows 2003 and IIS6.

Any help would be much appreciated.

thanks
