Any way to re-use the Channel..

[Wesly smith]

It could be dummy question ...

I tried to cache and re-use the channels in http case.
Is there any way to achieve that?

Currently, the way I am doing roughly is:
===================
// first time, I getChannel from future.

Channel c = future.getChannel();
...
c.write(httpMsg);
// cache the channels
cachedChannels.appendChannel(); 
...
// then in the messageReceived()
// It seems I have to disconnect(), otherwise, the transaction wont finish.
event.getChannel().disconnect();

// later I want to re-use the channel and get this channel from cache.
Channel ch = cachedChannels.getFreeChannel();
if (ch.isConnected() == false)
{
   future = ch.connect(address);
}

But I got ClosedChannelException:
NioClientSocketChannel(id: 48a7cec7-011e-1000-b33c-018557bf3f5e) - (cause:
ClosedChannelException) java.nio.channels.ClosedChannelException

====
Any idea or suggestion about re-use the Channel? I hope it will give me some
performance advantage.
