Hello!
I am using nginx in reverse proxy mode. When nginx proxy pass the certificates upstream, I would also like to pass the full cert chain along with it.
This is for an industrial application and I don't have full control on why it is done this way. The only thing I can tamper with is Nginx.
Digging around a bit, I found out that getting the cert chain through an environment variable is not possible: https://forum.nginx.org/read.php?2,288553,288553#msg-288553.
However, if I write a custom module, is it possible to get the intermediate certificate? Would you know which place in the code I should look at?
Thank you!
