<p>Note: Some server implementations additionally include a 307 status code (signifying a 'kick', i.e. a forced ejection from the
room). This is generally not advisable, as these types of disconnects may be frequent in the presence of poor network conditions
and they are not linked to any user (e.g. moderator) action that the 307 code usually indicates. It is therefore recommended for the
client to ignore the 307 code if a 333 status code is present.</p>
