About

The Content-Security-Policy HTTP response header and meta tag are used to control what resources a given page can load.

QUIC is a transport layer network protocol built on UDP that provides encrypted, low-latency data transfer, underpins HTTP/3, and was originally developed by Google.

It combines transport and security in a single protocol, establishes connections in as little as one round trip, supports multiple independent streams within a single connection to avoid blocking, and preserves sessions when a device changes IP address or network.
