Finesse internal agent reachability check?

[wmelick]

Does anyone know the mechanism Finesse uses internally to check the reachability of an agent?   I am asking because we are getting some reports of agents on VPN (AnyConnect) getting disconnected from Finesse.   Is there something like a timer which every X milliseconds checks the agent client app running on the browser?

Finesse uses BOSH https://en.m.wikipedia.org/wiki/BOSH_(protocol) to transport XMPP. If anything disrupts that connection the agent will be logged out after one minute.

Thank you Jonathan.  I will check that out....

Your response led me to an excellent doc I wanted to share with the community:
