It is a common problem when a page hosted on one domain can’t access data from a different domain. For example, if you have a page hosted on http://app.mydomain.com, which tries to load data from the http://data.mydomain.com, the data loading will fail. Any browser blocks such kind of data loading operation for safety reasons. Webix's found a solution for this problem. It can use two techniques to overcome the pitfalls of data loading: cross-origin resource sharing and JSONP.
