I have a site in asp and as you know asp is not case senstive. Because of this am facing a problem: Google is indexing my page with http://www.abc.co.uk/Phone_Deal.asp?Ph=White and http://www.abc.co.uk/Phone_deal.asp?Ph=White but in reality it is same page as different page. Plz how i can redirect to same page or when page with "Phone_deal.asp" this requested than 404 should be come.
if you want it not to index the querystring driven links - just add a nofollow to the link (if that is what you mean)
