[Freeswitch-users] Is curl.run() blocking until a result is got

Dear All, In the below example from FS wiki, can I be sure that "my_callback" will be called before session.hangup() is excuted? Thanks a lot Jasper use("CURL"); function my_callback(string, arg) { console_log("info", string); return true; } if (session.ready()) { session.answer(); var curl = new CURL(); curl.run("POST", "http://www.freeswitch.org/curltest/", "foo=bar&this=has+spaces+in+it", my_callback, "my arg\n", "user:s3cr3tpw"); session.hangup(); }
