So if I understand you correctly, you just want to keep reading the data
asynchronously and process them without sending them back?
Basically remove the ba::async_write from handle_read them, put your
processing code there within the if(!error)-Block instead and then after
processing just start another read the same way it is done in
handle_write (you don't need handle_write anymore then):

..
if (!error)
{
  process(data_);
  socket_.async_read_some(boost::asio::buffer(data_, max_length),
    boost::bind(&session::handle_read, this,
      boost::asio::placeholders::error,
      boost::asio::placeholder::bytes_transferred));
}
..
