What is CSP?

Content Security Policy – or CSP – is a security feature of modern browsers. Browsers will ignore data from domains that are not cleared in the CSP http-response header. For instance if you embed a YouTube movie on a webpage and the domain is not whitelisted in the CSP header, then the movie will not be loaded. All traffic from will be blocked and the movie cannot be displayed.
