It is a WordPress configuration, which relies on the nginx-proxy-cache-purge plugin to purge pages on update.
[code]
/etc/nginx/my.conf# cat wordpress-fastcgi-cache.conf
# Segment to include in all WP installs.
# Configures php-fpm (socket) with fastcgi caching.
set $nocache "";
if ($http_cookie ~ (comment_author_.*|wordpress_logged_in.*|wp-postpass_.*)) {
set $nocache "Y";
}

fastcgi_pass unix:/usr/local/var/run/php-fpm.sock;
fastcgi_index index.php;
fastcgi_param CONTENT-LENGTH $content_length;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_script_name;
include fastcgi_params;

fastcgi_cache_use_stale error timeout invalid_header http_500;
