As i mentioned , in my first email , i want to identify new index for each content message which should be calculate before forwarding the content and according to this content the nodes decide to cache and forward the content message or drop it

Then, I would like to say that something is not clear for me. there are 2 folders : (NFD/daemon/table and  util/trie)   that contain for example cs-policy-lru.cpp and lru-policy.hpp related to lru policy. I should copy these files and change them according my policy or just changing file in NFD path ? moreover, why in NFD/deamon/table path there are only files for lru and fifo policies not other policies.
>> furthermore, if I do not change forward.cpp still before forwarding the Data message can be dropped according the policy in  Policy::doAfterInsert function?
