A liquid containment berm and its method of creation, assembly and use, wherein the berm has one or more interior seal members, a floor member and an outer wall member created by applying an expandable foam polymer along a desired retention or flow control pathway, the foam polymer expanding to form the liquid impermeable outer wall member. A sending agent, associated with the document source and in communication with the communications network, sends the document to an intended destination address associated with the document consumer. One or more communication channels can be set up between the client and the server. This may provide for an improved energy-resolved photon counting. If the one service acceptor is unable to process the request, the one service acceptor determines if another service acceptor is able to process the request and notifies the middleware software.
