[Ndn-interest] Producing new contents with same name

Dear all,

  I have questions regarding producing new contents with the same name.
  Sorry if they are duplicate questions.

  Suppose that my consumer always wants to fetch 'fresh' data from a producer (the interest should not hit the caches of intermediate routers). Also, the consumer wants to use the same name to do so.

1. Is it allowed to produce different contents with same name?

2. If it is allowed, what would be a conventional way to implement it? My thoughts are:
- the interest of the consumer 'must be fresh'
- the producer produces the contents with the minimal freshness period (0 or 1).

3. If there is any other conventional way of fetching the newest version of contents, please let me know. As we discussed in the NDN seminar, the selector (right most child) does not solve the problem as it can sometimes retrieve old cached data.

Best wishes,
