Re: $http_rs shows 401 even when final response is 201 (http_async_query + Basic Auth)

Hi,
thank you for reporting. This is not what I would expect, honestly I don't
remember having faced this issue when I implemented this.
I went quickly through the code and I don't understand the reason for
returning 401, since $http_rs is a wrapper around core function get_status
which get the result code of a SIP reply (HTTP's ones are treated the same
way).
I will look deeper in the next few days.

Regards,

Federico
