Stateless protocol

In computer science, statelessness refers to the property of a protocol or system, multiple requests - even of the same principal - basically treated as independent transactions. In particular, queries without reference to earlier requests are handled and exchanged no session information and / or managed. The opposite is Zustandsbehaftung or state Entertaining.

Examples

Probably the most popular example of a stateless network protocol is the Hypertext Transfer Protocol (HTTP). The carrying of session data can here only be implemented at the application level, for example by explicitly sending a session ID in each request in a request URL or " Cookie" header.

As a counter- example of a stateful protocol can be cited, for example, the File Transfer Protocol (FTP). Here is a session is established only through an introductory authentication and authorization information provided by that on the logged in user applied to any subsequent request.
