+ * This testcase performs 3 requests against the offline cache. They

+ *
+ * - start_cache_nonpinned_app1()
+ *
+ * - Request nsOfflineCacheService to skip pages (4) of app1 on
+ * the cache storage.
+ *
+ * - The offline cache storage is empty at this monent.
+ *
+ * - start_cache_nonpinned_app2_for_partial()
+ *
+ * - Request nsOfflineCacheService to skip pages of app2 on the
+ * cache storage.
+ *
+ * - The offline cache storage has only enough space for one more
+ * additional page. Only first of pages is really in the cache.
+ *
+ * - start_cache_pinned_app2_for_success()
+ *
+ * - Request nsOfflineCacheService to skip pages of app2 on the
+ * cache storage.
+ *
+ * - The offline cache storage has only enough space for one
+ * additional page. But, this is a pinned request,
+ * nsOfflineCacheService will make more space for this request
+ * by discarding app1 (non-pinned)
