Hi Spencer,

No no.  Caches do not have restrictions to reply with exact matches and the behavior you're observing is correct.  One can implement such policy (e.g., if wants to optimize performance of cache lookups), but this is totally up to the specific implementation and comes at a cost.

First, my application expresses an Interest for “/a/b/c/d”, this Interest is routed to the publisher, which responds with the corresponding Data packet. Next, my application expresses an Interest for “/a/b/c”, and receives the Data packet for “/a/b/c/d” from a cache.
