Remarks
This terminology is defined in WebSocket RFC 6455, which is the time between unsolicited Pong control frames sent by the client to the server. The PONG serves as a unidirectional heartbeat and can be used for the client to determine network connection issues.
Note
Setting the DesiredUnsolicitedPongInterval on a StreamWebSocket associated with a ControlChannelTrigger is not supported. Setting the property does not change the actual interval.
Even though a custom unsolicited PONG interval is not supported with a ControlChannelTrigger WebSocket, the ControlChannelTrigger is impacted by two types of keep-alive intervals (1) network keep-alive interval and (2) server keep-alive interval. See ControlChannelTrigger Remarks for details. The server keep-alive interval can be configured through ControlChannelTrigger’s ServerKeepAliveIntervalInMinutes property while implementing application level PONGs.
