HTTP DELETE请求产生的状态501未在Google chrome和firefox中实现

Question

I am building an application in angular js with REST api. When I emit this REST DELETE request

DELETE http://localhost:8080/api/users/testlogin HTTP/1.1
Host: localhost:8080
Proxy-Connection: keep-alive
Accept: application/json, text/plain, */*
Origin: http://localhost:8080

I get on Google chrome Version 49.0.2623.112 m (64-bit) and Firefox Developer Edition 47.0a2 (2016-04-12), the response

Request URL: http://localhost:8080/api/users/testlogin
Request Method: DELETE
Status Code: 501 Not Implemented
Remote Address:127.0.0.1:9614

The weird part is the same operation succeeded in IE 11. The request above works too when using Advanced REST client chrome app (it produces status 200 and it does what it's supposed to do :) ).

In IE, the request contains

Request DELETE /api/users/testlogin HTTP/1.1

Code that performs Delete (angularjs v1.4.8) :
Controller:

angular.module('myApp')
.controller('UserDeleteController', function($scope, $uibModalInstance, entity, User) {

    $scope.user = entity;
    $scope.clear = function() {
        $uibModalInstance.dismiss('cancel');
    };
    $scope.confirmDelete = function (login) {
        User.delete({login: login},
            function () {
                $uibModalInstance.close(true);
            });
    };
});

Resource:

angular.module('myApp')
.factory('User', function ($resource) {
    return $resource('api/users/:login', {}, {
        'query': {method: 'GET', isArray: true},
        'get': {
            method: 'GET',
            transformResponse: function (data) {
                data = angular.fromJson(data);
                return data;
            }
        },
        'save': { method:'POST' },
        'update': { method:'PUT' },
        'delete':{ method:'DELETE'}
    });
})

Any idea why this behavior ??

Solved by invalidating intellij cache and clearing browser cache too. Guess I'll need to add a cache buster in prod :).
