AngularJS $http error function never called -

i have simple code :

$http.get("/api/test")     .success(function (data, status, headers, config) {         console.log(data);         return data;     }).error(function (data, status, headers, config) {         alert("error");         return status; }); 

it works fine, error function never called, when return 404 (not found) server... in case calls 'success' function status = 404...

is correct?

thanks

fiddler:

the problem webserver, setting content-length 0 means valid value can see on http/1.1 specification.

also made example on jsfiddle showing error , success examples. see here.

the headers error example:
