Hello! Function, passed to server->post() is called only from within wt event loop (which means in particular that wApp points proper application object) and only if current application is alive. So, you need not to check that application is alive.
By the way, you can pass another function to server->post() (as third argument aka fallBackFunction) which will be called if current application died.
