Caching issues?

[erus00]

Hi Karl,

Apparently I am experiencing a caching issue after importing a shop (woocommerce). The cart does not reflect what is added in it, it is showing "empty cart" for logged out users and working fine if logged in. I spent the day on this and just can't figure it out.

I used cachtool to flush the cache but this is not having any effect on the issue. php cachetool.phar opcache:reset --fcgi=/run/php-fpm/user1.sock

Questions: Is there a way to prevent the cart from being cached? What is the cache in place with nginx-more?

Thanks a lot

Hi Karl,

in 'etc/nginx/conf.d/custom/fpm-wordpress-cache-users.conf" I added "/cart/ " to:

if ($request_uri ~* "/cart/|/wp-admin/|/xmlrpc.php|wp-.*.php|/feed/|index.php|sitemap(_index)?.xml") {
        set $skip_cache 1;
}

It seems to be working fine. Would you think this is the best way to do it or would you advise otherwise?

Thanks

Hi,

You should be good with the following on WooCommerce:

if ( $cookie_woocommerce_items_in_cart = "1" ){
     set $skip_cache 1;
}

if ($request_uri ~* "/(cart|checkout|my-account)/*$") {
     set $skip_cache 1;
}

I will update the wordpress cache templates on next update to support WooCommerce.

Thanks

Hi Karl,

Thanks for that, I implemented it and it works perfectly.

Could you please let me know what is the best way to purge the cache by the terminal?

Visiting site_url/purge/ after putting my IP in /etc/nginx/conf.d/custom/admin-ips.conf is OK but I am looking for a more practical way that could also be used in a script.

Thank you very much.

Add an alias such as: alias purge-nginx-cache="rm -rf /var/lib/nginx/cache/fastcgi/*"

Visiting site_url/purge/ after putting my IP in /etc/nginx/conf.d/custom/admin-ips.conf is OK but I am looking for a more practical way that could also be used in a script.

This plugin works well to clear single page cache after editing: https://en-ca.wordpress.org/plugins/nginx-helper/
