public class RequestScopeManager
A RequestScopeManager manages a set of hierarchies that are meant to hold "request-scoped" objects. Each hierarchy is associated with a key. One can ask for the hierarchy corresponding to a specified key, which will return or create the Context at the top of that hierarchy.
In normal use, a server will spin off a number of threads that will handle requests. Those threads will each have a request object which is used as the key for its request scope.
