This doesn't seem to be working for me. Here's an example of what I'm
trying to accomplish:

I have a local backend that returns a response that includes
X-Accel-Redirect, Authorization, and Some-Other-Header headers among
others.
And I have a /remote-proxy location whose job it is to proxy the
X-Accel-Redirect to a remote server.
See example configuration below.

I would like the proxy-pass request to the remote server to include
the Authorization and Some-Other-Header headers that were returned in
the local backend upstream response.

I've tried to use the proxy_pass_header directive, but haven't had
much luck as my "custom" headers aren't being passed to the remote
proxy server.

Am I using these directives correctly? Is what I'm trying to do impossible?

Thanks,
Brendan
