Thanks for the information i don't use proxy_pass and the setup of php is as
shown here.
https://docs.joomla.org/Nginx
But i think based of what you said i should be able to add that same
"X-Accel-Expires" header to my PHP output itself and that will achieve it.
Might even be better since i can define that header on specific pages.
I will give it a try adding it to my PHP script and post back if it works or
not.
