About
The ETag HTTP response header is an identifier for a specific version of a resource that is used for cache validation.
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.
