Hi folks!

I have an nginx instance to proxy requests for a service that I have and I'm having trouble passing trailers.

If I curl my service directly I see the appropriate trailers that I set-up be returned. However I don't see the trailers when I curl on nginx which leads me to believe nginx is stripping the trailers.

I added a "TE: trailers" header to our request and in our nginx configs tried using:
"add_trailer Xstatus $sent_trailer_xstatus" and even
"add_trailer Xstatus $upstream_trailer_xstatus"
But I still don't see the trailers being returned
Is there any way to get trailers working with "proxy_pass"?

Could it be that we're just calling the wrong variable?
And is there any way to see _all_ the template variable values returned by the req?
