Handle Errors for Http and Ajax requests using HandleError Attribute Class

Question

I am handling all the errors in controllers using the HandleError Attribute which i have modified for for http and ajax requests, and handling them as a 500 error type.

public class HandleExceptionsAttribute : HandleErrorAttribute
{
    public override void OnException(ExceptionContext filterContext)
    {
        if (filterContext.ExceptionHandled)
            return;
        else
        {
            ErrorLogger.LogException(filterContext);

            if (filterContext.HttpContext.Request.IsAjaxRequest() && filterContext.Exception != null)
            {
                filterContext.HttpContext.Response.StatusCode = (int)HttpStatusCode.InternalServerError;

                filterContext.Result = new JsonResult
                {
                    Data = new
                    {
                        success = false,
                        message = "error",
                    },
                    JsonRequestBehavior = JsonRequestBehavior.AllowGet
                };
            }
            else
            {
                base.OnException(filterContext);
            }

            filterContext.ExceptionHandled = true;
            filterContext.HttpContext.Response.Clear();
        }
    }
}

and using it on each controller as:

[HandleExceptions]
public class InvoiceController : Controller
{}

I have also mode on the customErrors in web.config as:

<customErrors mode="On" >
  <error statusCode="400" redirect="Home/Error400" />
  <error statusCode="401" redirect="Home/Error401" />
  <error statusCode="403" redirect="Home/Error403" />
  <error statusCode="500" redirect="/Home/Error" />
</customErrors>

and the httpErrors as:

<httpErrors errorMode="Custom" existingResponse="Replace">
  <!--<remove statusCode="404" subStatusCode="-1" />-->
  <error statusCode="404" path="/Home/Error404" responseMode="ExecuteURL"/>
  <!--<remove statusCode="500" subStatusCode="-1" />-->
  <error statusCode="500" path="/Home/Error" responseMode="ExecuteURL"/>
</httpErrors>

The problem with me is that when I just uncomment the remove tag for status code then it's work fine with httpErrors but not with ajax request because instead of returning the status code it returns the Home/Error page. But if i comment this tag then httpErrors not return error page in most cases but work fine for ajax request which i can get in statusCode.

$.ajax({
            url: "@Url.Action("SomeAction", "SomeController")",
            type: "POST",
            async: true,
            cache: false,
            data: JSON.stringify(data),
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (response) {
                if (response.success) {
                    catchSuccess("Success", response.responseText);
                }
                else {
                    catchWarning("Error", response.responseText);
                }
            },
            Error: function (ex) {
                catchError("Unkown Error", "Contact the Administrator");
            },
            statusCode: {
                500: function () {
                    catchError("Error 500", "Internal Server Error. Contact the Administrator");
                },
                403: function () {
                    catchError("Error 403", "Internal Server Error. Contact the Administrator");
                },
                404: function (response) {
                    catchError("Error 404", "Internal Server Error. Contact the Administrator");
                }
            }
        });

What should I do to catch both side errors? Ajax request errors: I want to return the status code Http request errors: I want to return the page from an action. (Home/Error).

Answer 1

As it is working I am posting solution as answer. For above issue instead of checking statuscode check error in Jquery AJAX. Sysntax for the same is

error:Function( jqXHR jqXHR, String textStatus, String errorThrown ).

Try to log output to console or alert to check desired result to handle.

And if you want to handle specific response then throw specific error not generic one.
