The transform applied by the server on the stored resource MUST be repeatable and not dependent on seeing that transform in future PUTs to the same resource. This comes from partially the fact that PUT is a non-indempotent request, just as GET/DELETE. There must be no harm done on the server by repeating the same PUT. Regards Henrik
