*In computing, a stateless protocol is a communications protocol that treats each request as an independent transaction that is unrelated to any previous request so that the communication consists of independent pairs of request and response. A stateless protocol does not require the server to retain session information or status about each communications partner for the duration of multiple requests. In contrast, a protocol which requires keeping of the internal state on the server is known as a stateful protocol.

Examples of stateless protocols include the Internet Protocol (IP) which is the foundation for the Internet, and the Hyper Text Transfer Protocol (HTTP) which is the foundation of data communication for the World Wide Web.*
