[Ndn-interest] Ndn-interest Digest, Vol 55, Issue 16

[Ishita Dasgupta]

Hi All,

As a follow up to the previous email, I also edited the forwarding strategy
in cs and still no cache hits. Here is what my strategy list looks like.
Rest of it is similar to in the previous email.

> strategy=/localhost/nfd/strategy/best-route/%FD%05*


It would be really helpful if someone could provide an insight as to what I
might be missing here? My individual file sizes are not more than the cache
size (256MB).
