There is one specific call in our WordPress / WooCommerce installation that is using a lot of resources.
I would like to block this specific call to
downloads.infusedaddons.com
I believe it is simply checking for plugin updates in a very inefficient way.
I found that with the line...
define('WP_HTTP_BLOCK_EXTERNAL', true);
... I could block all calls and with the line...
define('WP_ACCESSIBLE_HOSTS', 'site1.com, site2.com');
... I then could allow specific sites to be allowed.
But this approach is too restrictive for our installation. Honestly I don't exactly know all external services that need to be allowed with this configuration. I already brought the email service down for a few hours.
So the best solution would be for me to specifically block this one external call.
How can I do it?
