About
The Content-Security-Policy (CSP) HTTP response header and 
HTML meta tag define which external websites a web page can load content from.
They help prevent attacks such as cross-site scripting (XSS) and data injection by blocking content from untrusted sources.
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.
