[ndnSIM] How to cache data in leafNode without request?

[Spyridon (Spyros) Mastorakis]

Hi,

you can write a custom application (or use the already provided consumer application) that will be sending Interests towards the producer to warm up the caches before you actually start your main experiment (for example, 5 - 10 seconds). 

After that, you can stop this application and start the main experiment.

Thanks,

So, I want the first information pre-loading to reduce the delay. But I don't know how to do in the ndnSIM.
