Exception thrown when the `RequestBuilder` attempts to make a request to a URL which violates the Same-Origin Security Policy.

Note: this exception will only be thrown by browsers that do not support CORS, i.e. Internet Explorer up to version 9. All other browsers will instead return a `status code` of 0. Internet Explorer can also be configured to allow such cross-origin requests without error and without using CORS.
