AngularJS: Under what specific circumstances is a promise returned by $http rejected? -

i'm pretty new angular (or javascript in general) , have dumb question here. understand how promises work, under specific circumstances promise returned $http request ( put or get or whatever) rejected? i'm pretty sure if request times out promise rejected; other errors 404 or 403? couldn't find such information angular docs... lot! if somehow $http error occur, promise rejected. $httpprovider based on interceptor pattern , every request/response pass through pipeline handles error. the default interceptor, built in angularjs this, reject promise: 'responseerror': function(rejection) { // on error if (canrecover(rejection)) { return responseornewpromise } return $q.reject(rejection); //<------ rejecting promise here given http error } you can build , attach own interceptor inside $httpprovider handle specific errors (400, 500, etc). take @ interceptor section, under $http documentation.
