I'm using the following header on a php page.



 // Prevent page caching.
header('Expires: Tue, 20 Oct 1981 05:00:00 GMT');
header('Cache-Control: no-store, no-cache, must-revalidate');
header('Cache-Control: post-check=0, pre-check=0', FALSE);
header('Pragma: no-cache');


I'm also using a rand=999999999 (with a real random number) in the URLs.



But pages are still being cached. Reload works, but first load is cached. Anyone know where I can change this?

          You send a duplicate "Cache-Control" header. Try removing the second one.

            Check NGINX settings. Might be there something like



            proxy_ignore_headers  "Cache-Control" "Expires";
