passing data between ChannelHandlers

[Matt DeLuco]

Is it possible to pass data between ChannelHandlers, or store data
somewhere that the handlers in a specific pipeline/channel can access
throughout the lifetime of the request?

For example, I have my own class for dealing with http cookies,
"CookieMap".  I'd like to have a SimpleChannelHandler that creates a
CookieMap to be used by handlers further upstream, and then sets the
cookies in the CookieMap on the response on their way back downstream.
