[ndnSIM] Intermediate routers don't cache objects

[Biozid Bostami]

Hello Everyone,I am new to ndnsim.I am facing this problem for a quite some time even though i set a content store on each node between the consumer and producer but only the node attached to the consumer is able to cache the items not the other nodes. So, i kindly request to help me this regard. 
yours faithfully,Biozid Bostami
