To communicate the Content Security Policy (CSP) as defined by the W3C, the web server needs to send a HTTP header to the browser (client) to inform it about the content security policies that SHALL be applied on the client. This draft outlines the header to communicate the CSP with its fields. The definition of the semantic of the directives will be done by the Web Application Security Working Group at the W3C.
