How to check response code from redirect url when redirecting in nginx?

Question

Nginx

Good afternoon,
There are two domains domain.com and domain.org, at the moment all requests are redirected from com to org with the corresponding uri. Is it possible to check the response code from .org with such a uri before redirecting and if it is not 200, just return it without any redirects? It must be done using the nginx server. Thanks for answers.

Answer 1

As far as I know, this cannot be done with standard directives.
However, you can write a few lines in Lua - then everything will be wonderful.
