I have a issue regarding exception throwing and catching on client side. This has all worked well until I introduced HTTP401. This is my base controler than overrides OnExcpetion:
protected override void OnException(ExceptionContext filterContext)
{
var exception = HandleException.Handle(filterContext.Exception);
filterContext.Exception = exception;
if(exception is AuthenticationException)
filterContext.HttpContext.Response.StatusCode = 401;
else
filterContext.HttpContext.Response.StatusCode = 500;
filterContext.ExceptionHandled = true;
filterContext.Result = new JsonResult()
{
Data = new { Message = filterContext.Exception.Message },
ContentType = "json"
};
}
This is my AJAX call along with succes and error.
$.ajax(
{
type: 'POST',
url: loginRoute,
data: formData,
dataType: 'json',
processData: false,
contentType: false,
statusCode: {
401: function () {
$('#authenticationErrorMessage').text(xhr.responseJSON.Message);
$('#authenticationError').show();
}
},
success: function (responseData) {
$('#authenticationSucessMessage').text(responseData.Message);
$('#authenticationSuccess').show();
window.location.replace(responseData.Redirect);
},
error: function (xhr, ajaxOptions, thrownError) {
$('#authenticationErrorMessage').text(xhr.responseJSON.Message);
$('#authenticationError').show();
}
});
The problems is that neither status code nor error are called upon completion. Only success is called. If I set my StatusCode to 500 all works fine.

You can globally handle it. May be below code help you.
$( document ).ajaxError(function( event, jqxhr, settings, exception ) {
if ( jqxhr.status== 401 ) {
alert( "Triggered ajaxError handler." );
}
});
