Matching H-sDFuSdC

CP-H-sDFuSdC+DS

Finds a process that reads (needs) data sent over a channel from a client and not saved on its host, and a second channel to the process from a distinct client, plus the process host. Adds a cache copy of the data flow on the host. The data need not be forwarded to the second client, but it still has to be saved because it is a necessary input that must be available when next processing requests for the second client.
