from the url: When the Apache HTTP Server manages its child processes, it needs a way to wake up processes that are listening for new connections. To do this, it sends a simple HTTP request back to itself. So, why apache want to wake up child processes periodically? It can do this based on event mechanism, only when new request is coming in, the child will be woken up. thanks.
