> When a servlet service request is created, parameters from the parent request are ignored. This means that the sub request is performed as a fresh and clean new call. This would avoid any possible side-effects, but is very inconvenient in practice because you don't even know the request header parameters from the original (external) request. Additionally you can only pass information which is part of the returned stream, which is e.g. a  blocker to use the servlet protocol together with the control flow implementations. Those make use of special request parameters to transport the model ("bizdata") to the view layer.
