Content-Security-Policy, X-Content-Security-Policy, X-WebKit-CSP

O cabeçalho de resposta HTTP Content-Security-Policy permite aos administradores de sites controlar os recursos que o navegador ou agente de usurio (user agent) pode carregar em uma determinada página. Com algumas exceções, as políticas envolvem principalmente especificar as origens do servidor e os endpoints de script. Isso ajuda a proteger contra ataques de XSS.

O cabeçalho de respsota HTTP X-Content-Security-Policy é requerido para implementar o CSP no Internet Explorer 10 e 11.

O cabealho de resposta HTTTP X-Webkit-CSP é requerido para implementar o CSP em versões mais antigas do Google Chrome, Safari e outros navegadores baseados na engine WebKit.

Para navegadores modernos, o cabeçalho Content-Security-Policy deve ser usado.
