protected void sendToLogin(java.net.Socket socket)

This function checks the login threads to determine the lightest loaded and adds the incoming connection to the thread.

Parameters:

socket - the incoming connection to pass on.

getLightestLogin

protected LoginThread getLightestLogin()

This function returns the lightest loaded login thread. Any thread with a connection count of 0 is used, else the thread with the lowest number of connections.

Returns:

LoginThread found.
