InitPrefix ensures the prefix is initialized for HTTP too, as WS and HTTP can share the same tree of configuration (and all the HTTP options apply to the initial upgrade).

WSConfigHeartbeatInterval is the frequency of ping/pong requests, and also used for the timeout to receive a response to the heartbeat.

WSConfigKeyInitialConnectAttempts sets how many times the websocket should attempt to connect on startup, before failing (after initial connection, retry is indefinite).

WSConfigKeyPath if set will define the path to connect to - allows sharing of the same URL between HTTP and WebSocket connection info.

WSConfigKeyReadBufferSize is the read buffer size.

WSConfigKeyWriteBufferSize is the write buffer size.

WSSpecificConfPrefix is the sub-section of the http config options that contains websocket specific config.
