    /* Description of the test:
     * We load resources (img, script, sytle, etc) over *http* and
     * make sure they do not get upgraded to *https* because
     * https-first only applies to top-level requests.
     *
     * In detail:
     * We perform an XHR request to the *.sjs file which is processed async on
     * the server and waits till all the requests were processed by the server.
     * Once the server received all the different requests, the server responds
     * to the initial XHR request with an array of results which must match
     * the expected results from each test, making sure that all requests
     * received by the server (*.sjs) were actually *http* requests.
