Nginx No-cache of a page

Hello ,

we have a config as given below, but still pages are cached on the browser side until it is removed from the settings of chrome (we tested only on chrome but it is not stabil and this is enough for research)
I hope somebody has some experience about this problem

than you

server {
    error_log /etc/nginx/logs/human_check_errors ;
    listen xxxxxxxxx:80;
    access_log /etc/nginx/logs/human_check_logs main;
    root /home/php;
	


	location ~* \.(?:css|js)$ {
		expires           epoch;
	    
	}
	location ~* \.(?:ico|jpg|jpeg|gif|png|webp)$ {

I see this on response

expires=Sat, 26-Aug-2017 05:46:13 GMT

Open in new window

so it is cachable...

try

expires           off;

Open in new window

so you can control your pages from pages...

or put a negative time here, so it is never cached...

response should be like this:

Expires: Thu, 01 Jan 1970 00:00:01 GMT
Cache-Control: no-cache

Open in new window

The Expires header shows a date in the past and Cache-Control is set with no-cache, which tells the browser to always ask the server if there is a newer version of the file (using the ETag header, like before).

The first result is when i am blacklisted , blacklist page , second result is when i am whitelisted that i need to see the white list page on the browser.
But , while curl returning the real server page's values i am still getting the first blocked page on my browser when i refresh the page
