[Serusers] Setting the Route header

Hello, when I receive a certain request, I intend to insert a Route header and then forward that request to the URI in the Route header. But when loose_route is called, it prints: find_first_route(): No Route headers found loose_route(): There is no Route HF This is the part of the config file: # This would be done in a module function of my own, it is simplified: append_hf("Route: 10.10.10.80:5062"); # loose-route processing if (loose_route()) { t_relay(); break; }; Can anybody help me? How can I forward the request to the URI in the Route header that I previously inserted? It seems loose_route does not take into account changes, it looks at the request as it was received. Thank you very much.
