Help- how can I implement content centric caching in ns2?

how I can implement CCN caching strategy using NS2. I have followed the tutorial instructions but I still face difficulties to achieve my research idea. I created wired with wireless topology similar to existing wired-cum-wireless-sim.tcl file then I aim to integrate the http caching into it. I don't know if am I in right way or not. Can you guide me step by step?
