+/**
+ * Test for the "alternative data stream" - closing the stream with an error.
+ *
+ * - we load a URL with preference for an alt data (check what we get is the raw data,
+ *   since there was nothing previously cached)
+ * - we store something in alt data (using the asyncWait method)
+ * - then we abort the operation calling closeWithStatus()
+ * - we flush the HTTP cache
+ * - we reload the same URL using a new channel, again prefering the alt data be loaded
+ * - again we receive the data from the server.
