[Nfd-dev] [Ndn-app] Close NFD backdoor -- PLEAE LEAVE IT OPEN

[Giovanni Pau]

Dear All, 

This for the V2V case represents a problem, we relay a lot on caching unsolicited content to achieve higher delivery rate. The V2V environment is so harsh that you can’t miss any opportunity to grab a content that may be useful in the future.  

I would be more incline to find a compromise based on a configuration parameter (i.e. this becomes a configuration issue per face) or to enable unsolicited content caching if there are some trust mechanism, however for us is really essential to keep this feature alive.

Thanks 
Giovanni
