Nginx fails to receive custom header when Redirected by Proxy server Node

Question

I am running an NGINX server pointing to my proxy server which is running on Node. I am redirecting to app/ from node using express redirect. I am also passing a custom header using res.set("X-Custom-Header","XXX"); before the redirect. But the same header is not retrieved on app/ route on NGINX. Is there anything I am missing?

You are setting a response header. This is not the same as the request headers that are received by nginx from the client. — Richard Smith

Is there a way to retrieve this in nginx route as I need to check few conditional statements based on the response header — ajaykumar

By default, nginx does not pass headers containing underscores.

Try:

underscores_in_headers on;

See this document for details.
