How to 100% disable page caching?

Question

PHP

You need to disable caching for a specific page. I tried to use different html tags and send headers, but the effect is opposite. The page was both cached and cached (I checked the returned headers, they are sent with a request not to cache).
In PHP I tried this:

header("Cache-Control: no-store, no-cache, must-revalidate");
header("Pragma: no-cache");
header("Last-Modified: ".gmdate("D, d M Y H:i:s")."GMT");
header("Expires: ".gmdate("D, d M Y H:i:s")."GMT");

PS I'm already sinning on nginx, which is installed on the server as the only web server.

Answer 1

The client may have the wrong time. Substitute a date from the past in expires, just in case.
