            CacheManager.saveCacheFile(mUrl, mCacheResult);
        }

        // we need to reset mCacheResult to be null
        // resource loader's tearDown will call into WebCore's
        // nativeFinish, which in turn calls loader.cancel().
        // If we don't reset mCacheFile, the file will be deleted.
