After receiving and storing the Interest, the intermediate node will have to let them go. It seems that you should be looking at an application that combines both the functionality of a consumer and a producer and should be installed at the intermediate nodes.</div><div class=""><br class=""></div><div class="">Thanks,</div><div class=""><br class=""><div class="">
