I'm trying to add a link to a PDF on an external domain; e.g. cdn.hubspot.com and when I save the article, I get an immediate 403 error. From what I understand, this is the intended result with Admin Tools.
My question, is there a way to white label specific external domains? If so, how would that exception be written in the .htaccess file, assuming that is the correct place to do so.
Thank you,
John
