QUICType
About
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.
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.
