This class rewrites all URLs in the content sent by the producer
using rules listed in the 10.2 section of the WSRP spec and
information provided in its constructor.
These keys must be set as the channel keys in the provider context
by the caller of WSRPConsumer.
As an example, these keys are set
by the admin when a WSRP channel is created
If I think more, this is a missing piece
in the container interface architecture.
Each container needs certain information for
working from its client.
