As long as the reconstructed oldURL is the same as the original url you
start with, you could simply go there, discard the response, edit oldURL to
make it https, then go to that page.
Actually, if the redirect page doesn't send cookies or anything else, you
could probably just go direct to the https url without bothering to hit the
unsecure one.
Just because the page has javascript doesn't mean you have to evaluate it.
