Are Flask client side session stateless?

From what i've researched, Flask's sessions are by default on the client side. Wouldn't this mean that Flask by default is stateless?

No, Flask is not stateless, it has a built-in session implementation to hold state.

In addition to the request object there is also a second object called session which allows you to store information specific to a user from one request to the next.

Sessions by definition hold state. Wikipedia [1], [2]

HTTP sessions, which allow associating information with individual visitors

Cookies were designed to be a reliable mechanism for websites to remember stateful information

The HTTP request/response cycle, on it's own, is stateless. You use a session to persist state across requests. The form this session takes, whether it's a cookie stored client side, or a token to data stored server side, does not change the fact that a session is state.

Flask provides a way to override how sessions are handled. There are various extensions such as Flask-Login and Flask-Session which provide alternative ways to handle this, such as with a token and server-side session rather than the default cookie.
