[ndnSIM] multiple names

[Hafsteinn Hjartarson]

Thanks for the reply Spyridon!

Yes that is correct, I can retrieve different parts of the prefix as you
suggested but I see that I was a bit unclear.

I was really asking if this is how it should be done. That is, when an
application has to deal with multiple actions, it should break down the Uri
and use multiple "if" statements (like in my example).
Or is there a more "correct" way of handling this?

Another thing ... when an application receives an Interest, is it possible
to extract some kind of ID from the interest that identifies who sent it?

Best regards,
Hafsteinn
