+/*
+ * Description of the test:
+ * We test https-first behaviour with forms.
+ * We perform each test with once with same origin and the second time
+ * with a cross origin. We perform two GET form requests and two POST
+ * form requests.
+ * In more detail:
+ *
+ * 1. Test: Request that gets upgraded to https, GET form submission.
+ *
+ * 2. Test: Request that gets upgraded to https, that upgraded request
+ *          gets timed out, so https-first send an http request, GET form submission.
+ *
+ * 3. Test: request that gets upgraded to https, and sends a POST form
+ *          to http://example.com.
+ *
+ * 4. Test: Request where the https upgrade get timed out -> http, and sends a POST form
+ *          to http://example.com,
+ *
