[Ndn-interest] question

[Meng Kuai]

About this problem, I have a question.
Since there is no matching entry in content store, does the incoming
interest trigger application to generate content?

Thanks,

thanks for the question, and here is my understanding:
1/ keep in mind that NDN is a network layer protocol (thus it is not NDN
requesting content, but some application is asking for content, and an NDN
Interest packet will carry that request towards the content producer)

2/ Since one is asking for some data that does not exist yet, the Interest
will reach (one of) the server and server produced the requested data.
Web is doing today to produce dynamically tailored data for individual
users.

3/ the NDN network can then deliver that newly created content back to the
requestor.

Hope this answered your question?
