re: #94 Charles Johnson

The heartbeat function sends a periodic message to the server and the server sends it back, to make sure the connection is still open.

thank you, yes, but i have implemented many such ‘keep alive’ or ‘are you still there?’ mechanisms in the course of my career yet i never needed to have the process at the other end copy a string to its memory and then echo it back to me

i am asking what function does that part of the ‘heartbeat’ algorithm accomplish?
