Your first example is working because you are not using an Ajax callback --
the link is just a regular request for a full page. You second example
doesn't redirect the whole page because the callback is an Ajax request --
so, the redirect just returns the redirect output as the Ajax response, and
Ajax responses do not reload the whole page. Instead, you want to do a
client-side redirect, which will reload the page via Javascript on the
client side. Try:
redirect(URL('product'), client_side=True)
