How to get rid of caching completely

Is there a way to stop caching at all level?

I have added

  •    expires -1;*
  •    add_header Cache-Control "private, must-revalidate, 


  •    add_header Last-Modified "";*

this on my nginx server block, but there are still some caching are
happening. Any way to get rid of that completely. :slight_smile:
