IIUC, before using the translator handler, the ping data can be delivered from
the client to the runtime side since kube-apiserver does not parse any client
data. However, with WebSocket, the server responds with a pong to the client
without forwarding the data to the runtime side. If a proxy is present, it may
close the connection due to inactivity. SPDY's PingPeriod can help address this
issue.
