[mosquitto-dev] Session Resumption using Session IDs

["$@(#!N" <sachinjoshi4496@xxxxxxxxx>]

Hello,

I have 2 Paho-MQTT client programs (1-subscriber, 1-publisher) & Mosquitto broker v1.5. 

I have put TLS v1.2 in the client programs.

I was able to verify session resumption occurrence through Wireshark.

But what is the default session ID lifetime in seconds (When does it expire)?
