Mark Webb updated DIRMINA-350:
------------------------------

    Attachment: HeartbeatIdleFilter.java

Here is a class that will send a message to the remote client when the session becomes idle.  Here is an example of its usage:

ByteBuffer buffer = ByteBuffer.allocate(16);
buffer.put( Charset.defaultCharset().encode("heartbeat") );
buffer.flip();
HeartbeatIdleFilter hbf = new HeartbeatIdleFilter(buffer);
        
DefaultIoFilterChainBuilder chain = acceptor.getFilterChain();
chain.addLast("heartbeat", hbf);

> We need a filter that sends a certain message to the remote peer periodically to let the remote peer that the local peer is alive.  It is very easy to implement and will be very helpful.
