promise - How to cancel an $http request in AngularJS?

Question

Given a Ajax request in AngularJS

$http.get("/backend/").success(callback);

what is the most effective way to cancel that request if another request is launched (same backend, different parameters for instance).

Answer 1

This feature was added to the 1.1.5 release via a timeout parameter:

var canceler = $q.defer();
$http.get('/someUrl', {timeout: canceler.promise}).success(successCallback);
// later...
canceler.resolve();  // Aborts the $http request if it isn't finished.
