But the only point in this is to take down a site you won't be able to get into useful information back from this request as the request's response will be heading back to the spoofed address... (though if you are using for ddos it is pointless to get the data back...)

You can't make an HTTP request with a spoofed IP without being in position on the network to do a MiTM. The TCP handshake won't complete, so you can't send the HTTP request.
