Hello! Please help me to understand how http_async_client module behaves. I am going to use it for call routing according to the http response. if (is_method("INVITE")) { t_newtran(); xlog("L_ERR", "ASYNC0-$fU-$rU-$rm---- \n"); http_set_timeout(1000); http_set_method("POST"); http_append_header("Content-Type: application/json"); http_async_query("http://10.10.10.10:8080/RPC", "{\"jsonrpc\": \"2.0\", \"method\": \"ul.lookup\", \"params\": [\"location\",\"user\"], \"id\": 1}", "HTTP_REPLY"); xlog("L_ERR", "ASYNC1-$fU-$rU-$rm---- \n"); } route[HTTP_REPLY] { xlog("L_ERR", "HTTP_REPLY: ok $http_ok \n"); xlog("L_ERR", "HTTP_REPLY: status $http_rs\n"); xlog("L_ERR", "HTTP_REPLY: body $http_rb\n"); xlog("L_ERR", "HTTP_REPLY: error $http_err)\n"); } In syslog I see HTTP_REPLY log strings with correct response, but do not see ASYNC1 string and script execution stops.

So my config is ok and I need to add all next logic with call routing to route[HTTP_REPLY] ,correct ? 2018-09-27 16:42 GMT+03:00 Federico Cabiddu <federico.cabiddu(a)gmail.com >: > Hi, > if you are in a transactional contest (as you are since you are > calling t_newtran()), the script execution is suspended, upon calling > http_async_query and resumed in the callback route passed as parameter. > The instructions after the call to http_async_query are never > executed.

What do you mean with "does not work well "? I don't remember any change in that part but anyway you should switch to 5.0 or 5.1 releases, since those are the maintained ones.
