Hi Urs

What then happens when the (same as below) Interest
>
>         /nytimes/frontpage | CanBePrefix=true | MustBeFresh=true
>
> arrives at a cache with the sole content

>         /nytimes/frontpage/addBanner/v23 | 60'000ms

Yes, the cache will return the /nytimes/frontpage/addBanner/v23 Data.

My old article about web publishing over NDN
https://yoursunny.com/t/2011/ndn-web/ proposed a solution: the Data name
should include an extra component: /nytimes/frontpage/.../v105 (... denotes
a zero-length component, see NDN URI spec). The Interest is then
/nytimes/frontpage/... CanBePrefix=1 MustBeFresh=1, which cannot be
satisfied by /nytimes/frontpage/addBanner/v23.
