[SR-Users] Websockets Keep-Alive

[Peter Dunkley]

The Kamailio websocket module sends WebSocket pongs in response to
WebSocket pings from websocket clients.  It can also be configured to send
WebSocket pings on idle connections (and does so by default).

There is no TCP level stuff here, this is all at the WebSocket layer.  Take
a look at the "keepalive_.*" modparams for the websocket module.

The TCP connection timeout should be set to something a little greater than
the WebSocket ping interval is set to.

Regards,

Peter
