const ORIGIN_HEADER = "http://mochi.test:8888";

/* Description of the test:
*   We call sendBeacon() cross origin and make sure that the
*   origin header is actually set in the request.
*
* Since sendBeacon() does not expect any response, we are storing any
* header on the server (*.sjs) and use an XMLHttpRequest to actually
* retrieve the potentially set header back from the server. We assert
* that the header is indeed *not* sent with the request. Since sendBeacon()
* and also the XMLHttpRequest() are performed in an asynchronous fashion,
* there is no guarantee that the sendBeacon() is actually executed before
* the XMLHttpRequest().
* Hence the xhr-response might be processed asynchronously.
