Generating Cookie?

Hello,

We use Nginx Fastcgi cache on Woocommerce site.

On nginx, we set only each bypass if there is item in cart, otherwise, hit cache.

Recently, I noted that all cache are bypass, and that might be caused by Cookies.

I am not sure it is caused by Wp offload for now, would you please let us know if there is cookie generated by Wp offload please?

If yes, I noted there is CORS Configurations on Digitalocean space, will it be helpful to block or remove cookie? any tutorial please?

Thanks
