Q:

angularJS: custom 404 interceptor handle - response with url

In my app I use an interceptor to catch all http response errors, like:
var response = function(response) {
  if(response.config.url.indexOf('?page=') > -1) {
    skipException = true;
  }
  return response;
}

var responseError = function(rejection) {
  if (rejection.status === 401 || rejection.status === 403) {
    /**/
  }
  else if (rejection.status >= 500 || rejection.status === 0) {
    /**/
  }
  else if (rejection.status === 404 && !skipException) {
    /**/
  }
  else if (rejection.status === 404 && skipException) {
    /**/
  }
  else{
    /**/
  }
  return $q.reject(rejection);
};

And when I go to my controller (when my getArticles method returns some data, not 404 - when articles array is empty) all is OK: 404 with skipException == true is caught.
But when my articles array is empty the server returns a 404 and when I enter this controller I cannot get response.config.url -- no response is caught, but why?  I thought that interceptor would catch all of the responses.  
    $timeout(function() {
      $scope.getArticles();
    }, 100);

and $scope.getArticles has such code:
getDataService.getArticles($scope.pageNum).then(function(response) {
 /**/
});

service:
var getEventsByScrollService = function(num) {
  var deferred = $q.defer();
  $http.get(***, {

    })
    .success(function(response) {
      deferred.resolve(response);
    }).error(function(err, status) {
      if (status === 404){
        deferred.resolve([]);
      }
      else{
        deferred.reject(err);
      }
    });
  return deferred.promise;
};

How can I conditionally catch 404's depending on the URL?  Because this:
if(response.config.url.indexOf('?page=') > -1) { 

Doesn't always work.

A:

In an effort to be more maintainable and extendable to any $http service call one could do this:
// Service call
$http.get({url:'/?page=', ignoreErrors: true})

// Interceptor
if(rejection.status === 404 && !rejection.config.ignoreErrors) {

}

A:

so...
i have done it so:
    if(rejection.config.url.indexOf('?page=') > -1) {
      skipException = true;
    }
