Hi all,

For the OOD shell app, when I have ping-pong enabled (`OOD_SHELL_PING_PONG=true`), what is the effect of `OOD_SHELL_INACTIVE_TIMEOUT_MS` ?

My assumption is that the ping-pong signal would keep the connection active, and hence the inactive timeout would never be reached. However, I was wondering if the inactive timeout was still useful to handle some failure conditions for the ping-pong.

Thanks,  
Ron

Ping pongs do not count as activity (to us, it does to apache). `OOD_SHELL_INACTIVE_TIMEOUT_MS` is based on actual user activity which can disconnect you even if you’re keeping the TCP connection alive through pings.
