ingstr<>"" Then Query_Stringstr="?"&Query_Stringstr IF instr(Server_Name,"www.")<1 Then Response.Status = "301 Moved Permanently" if instr(Path_infostr,"index")>0 or instr(Path_infostr,"default")>0 Then Response.AddHeader "Location","

http://www."&Server_Name Else Response.AddHeader "Location","http://www."&Server_Name&Path_infostr&Query_Stringstr End if Response.End End if %>
