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.
