Definition

Type of WebSocket session handling

• Stateless:     For each incoming WebSocket message a new session is created in which the message is processed. Afterwards this session will be deleted. Multiple sessions can exist in parallel.
• Stateful:     A specific session is assigned to the WebSocket. All incoming WebSocket messages are processed in succession in this session.
• None:    This session handling can only occur temporarily when the client connection is closing. In this case the assignment of the WebSocket to this session has already been removed.

Client connections are always stateful (unless the connection is just closing). For server connections both types of session handling (stateless and stateful) are possible. If a WebSocket is stateful, the session assigned to the WebSocket can be removed from the column "Session Key".
