https://www.kamailio.org/docs/modules/stable/modules/http_async_client says $http_rr will be the HTTP reason phrase. I'm understanding this to mean:
Code: Reason: 200 OK 404 Not Found
In my current 5.4 build, $http_rr returns empty (not <null> or anything else) regardless of what the server sends in the headers.
Am I misunderstanding this? I'm writing an API and was hoping to do
send_reply("$http_rs", "$http_rr");
