Re^2: How do I make a tcp socket heartbeat?

Taking the opportunity, Could you tell me how I do if I wanted my client, when the server goes down, to try to reconnect?

Like, in the $stream->on(close => ...) how do try to I connect again to the server?

One way to do that is to place the `Mojo::IOLoop->client` call in a subroutine, as in `sub reconnect { Mojo::IOLoop->client( ... ) }`, make sure to call that `sub` once before starting the loop to set up the initial connection, and then, in the handler for the `close` event, do something like `Mojo::IOLoop->timer( 2 => \&reconnect );` to call that subroutine to reestablish the connection. I very much suggest the `timer` call so as to not flood the server with connection attempts, and I would also recommend adding a counter variable so you can stop attempting to reconnect after a certain number of failed attempts.
