Unfortunately you will not find one. Reverse Ajax is a complex task that requires both server side and client side "magic" in order to be cross-browser compatible, have proper state and thread management and be scalable. Essentially a comet server is a streaming connection per client (or long polling) + clever thread management.
In addition for a proper comet server you would have to fully implement the Bayeux protocol .
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
