[[Image:messages-logout.png|thumb|The client sends a logout request and the server accepts or denies it.]]

If the player is in some kind of combat it is often desirable to prevent him from saving his live by logging out. Therefore the client sends a logout request to the server and the game server can decide whether to accept or reject it. Of course the user can close the client window or force a disconnect of his Internet connection. But in these cases he will simple stay in a game unattended until the timeout anyway.

The clients indicates that it wants to finish the session by sending a [https://sourceforge.net/p/arianne/marauroa/ci/master/tree/src/marauroa/common/net/message/MessageC2SLogout.java C2SLogout].

The server can reply with a [https://sourceforge.net/p/arianne/marauroa/ci/master/tree/src/marauroa/common/net/message/MessageS2CLogoutNACK.java S2CLogoutNACK] to reject the logout request. Or it confirms the request with a [https://sourceforge.net/p/arianne/marauroa/ci/master/tree/src/marauroa/common/net/message/MessageS2CLogoutACK.java S2CLogoutACK]. In this case the client state is changed to logged out.
