- briansmith 18y agoAFAICT, you can have things on another domains if and only if nobody else but you is using the same objects on the same domain. But, anybody will be able to DoS you by simply linking to content on that domain. My understanding is that it works like this example: My domain is example.com and I have a CDN examplecdn.com for images (e.g. http://examplecdn.com/dog.jpg http://examplecdn.com/dog.jpg). Now, let's say an attacker posts a link to http://examplecdn.com/dog.jpg http://examplecdn.com/dog.jpg to Reddit and Digg. If a user visits example.com, Reddit, and Digg while they are all linking to that image, and if the user has his InPrivate Blocking level set to "3", that image will stop loading from all pages not hosted on examplecdn.com, including example.com.
