I made some tests and the query is, as I expected, considered as a part of the URI. Thus to receive bundles sent to [dtn://node1/app0?lang=en] I need to add a registration "app0?lang=en" by doing (from CLI) $dtnrecv --name "app0?lang=en".
Do I really need to add a registration of each single combination of parameter of the query, or is there a way to hack the daemon, without changing its source-code, to do this ?
Thanks for further replies, have a nice day !
