How to force clear user's browser cookies?

Question

Nginx

What nginx setting (nginx + php-fpm + mariadb bundle) will make it ignore old user browser cookies?

Answer 1

You can remove them on the nginx side when proxying

proxy_hide_header       Set-Cookie;
proxy_ignore_headers    Set-Cookie;
# important! Remember the special inheritance rules for proxy_set_header:
# http://nginx.org/ru/docs/http/ngx_http_proxy_module.html#proxy_set_header
proxy_set_header        Cookie "";

Answer 2

Send the same cookie with an expiration date in the past.
