Hi All,
After multiple interests are being sent for the same data, I still have 0
cache hits. I have set my cache byte size to 32768 bytes (256 MB) and
restarted the nfd daemon but I simply don't see anything being fetched from
the cache. Do I have to add the prefix for the interest in question in the
forwarding strategy section of the nfd.conf file? Or some flag that I have
to turn on?
*This is what nfdc-cs gives me:*
