passing data between ChannelHandlers

[Norman Maurer]

I was using it before in a project but remoted it in favor of
ChannelHandlerContext.setAttachment(..).

But it worked quited fine for me. You can see the old code here:

http://svn.apache.org/viewvc/james/protocols/tags/protocols-1.5/impl/src/main/java/org/apache/james/protocols/impl/AbstractChannelUpstreamHandler.java?view=markup

Bye,
Norman

Ps: What does not work for you ?
