+/**
+ * Check how nsICachingChannel.cacheOnlyMetadata works.
+ * - all channels involved in this test are set cacheOnlyMetadata = true
+ * - do a previously uncached request for a long living content
+ * - check we have downloaded the content from the server (channel provides it)
+ * - check the entry has metadata, but zero-length content
+ * - load the same URL again, now cached
+ * - check the channel is giving no content (no call to OnDataAvailable) but succeeds
+ * - repeat again, but for a different URL that is not cached (immediately expires)
+ * - only difference is that we get a newer version of the content from the server during the second request
