Use this ASP code to redirect your pages to a single site. Search engines may penalize you for duplicate content if they find content at yoursite.com and www.yoursite.com or multiple domains pointing at the same site.

If  lcase(Request.ServerVariables(“HTTP_HOST”))=”lyonscom.com” OR lcase(Request.ServerVariables(“HTTP_HOST”))=”www.sitenumber2.com” OR lcase(Request.ServerVariables(“HTTP_HOST”))=”sitenumber2.com” Then
 Response.Status = “301 Moved Permanently”
 If lCase(Request.ServerVariables(“URL”)) = “/default.asp” Then   ‘ change home page here
  If Len(Request.Querystring)=0 Then
   Response.AddHeader “Location”, “http://www.lyonscom.com/“
  Else
   Response.AddHeader “Location”, “http://www.lyonscom.com/?” & Request.Querystring
  End If
 Else
 If Len(Request.Querystring)=0 Then
   Response.AddHeader “Location”, “http://www.lyonscom.com” & Request.ServerVariables(“URL”)
  Else
   Response.AddHeader “Location”, “http://www.lyonscom.com” & Request.ServerVariables(“URL”) & “?” & Request.Querystring
  End If
 End If
 Response.End
End If

Note, the Response.Status line will tell the search engine crawler to remove the duplicate content and only index the conent at the new location.
