Hi,
I am using nginx version 1.10.1 with reverse proxy function toward
Apache 2.2.15 I noticed that if I change something inside backend (eg.
modify some text on some article), that changes appear on frontend, but
I still view old post's content into backend.
I tried to disable any caching mechanism for /wp-admin and /wp-login
 I hope I did this properly, can you help me in order to figure some
errors with this configuration?

This is my nginx global config:
####################################################user nginx
nginx;worker_processes 4;
