Hi Yakun,

If you want to create and send out a slightly modified Interest inside the forwarding strategy, you can do something similar to what is done in nacks.cc: you create a new Interest, based on the existing interest that you have and then "replace" necessary parts (name).  For example,

Ptr<Interest> newInterest = Create<Interest> (*header);
newInterest->SetName (Create<Name> ("/some/new/name"));

Ptr<Packet> packet = Create<Packet> ();
nonNackInterest->AddHeader (*nonNackHeader);

So I wanna add a new header similiar to Ptr<const InterestHeader> header in forwarding-strategy.cc except for the name. In other words, I wanna reset the name in Ptr<const InterestHeader> header.
