Описание тега stateless
Stateless apps don't expose any information about what has happened or changed since it started running
Stateless apps don't expose any information about what has happened or changed since it started running. They give the same response to the same request, function or method call, every time. HTTP is stateless in its raw form - if you do a GET to a particular URL, you get (theoretically) the same response every time. The exception of course is when we start adding statefulness on top, e.g. with ASP.NET web apps:) But if you think of a static website with only HTML files and images, you'll know what I mean.
