About
The Content-Security-Policy HTTP response header and meta tag are used to control what resources a given page can load.
HTTP (Hypertext Transfer Protocol) is an application-layer protocol used to transfer resources such as HTML documents, images, and other web content, forming the foundation of data communication in web browsers.
It uses a stateless request-response model between clients and servers, defines standard request methods such as GET and POST, uses headers for metadata and caching control, and typically operates over TCP or TLS in the case of HTTPS.
Modern versions such as HTTP/2 and HTTP/3 improve performance by introducing multiplexing over a single connection, header compression, and, in HTTP/3, QUIC over UDP to reduce latency and eliminate head-of-line blocking.
