I don't think I would use ICP for such configurations. More likely I
would use intra-array CARP routing or a similar design to make sure
objects get cached at designated places, and then add some heuristics to
this for intentional cache duplication.. (pollution is the wrong word
here.. you get pollution when invalid content enters the cache)
