And you *COULD* use
if you used URL-rewriting on the server.
That is, the server would see "test.js?id=5
" and know that, for this specific file request, it should rewrite that into "zamboni/frambot.php?zam=117&requested=5
We do something like that with some ".css" files on one server I work on.
It's easy to do that with Linux or Windows servers.
