Using the mirror module

[Peter Booth]

This is the point where I would jump to using the debug log. You need to build you nginx binary 
with —with-debug switch and change the log level to debug innginx.conf. Debug generates a *huge* 
amount of logs but it really is invaluable.

I would also want to double check what is actually happening and use ss or tcpdump 
to confirm that no request is sent to your staging destination.

 I’m assuming that both ww.example.com and staging.example.com are hosted 
on different hosts, different IPs and are both functional.
