Hi all,
I'm trying to access to the API REST of Zimbra with Angular.js e.g.

'use strict';
 .factory('calendarData', function ($resource) {

return $resource('https://mydomain:7071/home/davide/calendar?fmt=json',{ }, {
    getData: {method:'GET', isArray: false}
and I bogged down in the CORS trouble:

XMLHttpRequest cannot load https://mydomain:7071/home/davide/calendar?fmt=json.
No 'Access-Control-Allow-Origin' header is present on the requested resource.
Origin '' is therefore not allowed access.
What to do? How should I enclose CORS headers to Zimbra API? Thanks in advance for your support.
Thanks in advance for your help
