Thanks for that clarification. I believe this portion of that link would be still be relevant:
"If your application uses GET or HEAD requests for dynamic content and does
not include cache control headers, the server may return cached responses that do
not apply to the user.
To correct this issue, perform one of the following actions:
- Disable caching for the user in WHM’s NGINX Manager interface (WHM >> Home >> Software >> NGINX Manager).
- Modify your web application to use the appropriate headers so NGINX does not cache the request."
The specific configuration options you provided would work well with Apache, so these would not need to be placed in a separate area for the Nginx service, as our Nginx tools proxy requests to Apache. You would likely want to create a custom include file to apply that to the overall Apache configuration:
EasyApache 4 provides several ways for you to customize your Apache configuration.
