Okay. Thought it might be something like that, just wanted to be sure
before fuzzing the issue.

You will need to create an ACL just for this URL (an others you want to
do the same).
  acl objectX ...

proxyA needs to allow peers past the miss_access block.

proxyA:
  miss_access allow objectX
  miss_access deny siblings
  miss_access allow all

siblings must never go direct to the object (always use their parent peer)

proxyB/proxyC:
   never_direct allow objectX
