Notes
It should be noted that a website can be configured so that they are not allowed to be viewed through an iframe from a different website. In this case the iframe will load a blank page.
It should also be noted that some popular browsers disallow the loading of iframes which contain non-HTTPS content on webpages which are under HTTPS. This policy is called Mixed Content Blocking and has been the norm since at least 2013.
