+ * Test for the "alternative data stream" stored withing a cache entry.
+ *
+ * - 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 the alt data along the channel (to the cache entry)
+ * - we flush the HTTP cache
+ * - we reload the same URL using a new channel, again prefering the alt data be loaded
+ * - this time the alt data must arive
