"redirect" there means "send a http redirect to the client, so that
the client will make a fresh request using the new url". Which means
"the browser url bar will change", as you see.

In principle, replacing your "redirect" with "last" should Just Work. But
there is a separate issue, that when nginx does an internal rewrite,
only an explicit ? in the rewritten string causes the request to be
parsed as "url with query string".
Merely having a ? in the expanded-variable, is not enough.
So, one option could be to "proxy_pass http://127.0.0.1$new;"; (where the
scheme://host:port refer to this nginx server -- change as necessary)
instead of "rewrite" -- that is sort-of like an "internal" version of
the redirect. But it is probably overkill, if you can use the next
option instead:
Another option could be to change your map so that you have one variable
that is the query string (id=100; id=200; etc) and another variable that
is the url (/product.php); then you can "rewrite ^ $new?$newquery
last;", and it should do what you want.
(If all of your rewrites will go to /product.php, then you can hardcode
that bit and stick with the single variable.)
With this second option, you could also choose to move the "if($new)"
stanza outside of "location /", and have it at server level. I don't
think it is necessary; but it might be more efficient, depending on the
fraction of requests that set the variable.
Good luck with it,
