Why does that say host:localhost?

Is there any chance that something else in your system is using
X-Original-URI as well, and overwriting the header value you set?

Perhaps use "X-Testing $request_uri" in the nginx config and see if that
changes anything?

That seems unlikely to me.

Testing shows that it still works for me.

So, if you still see the problem, can you show a complete nginx config
and sample request that will let someone else see the same problem?

Good luck with it,
