Same, iOS 4.3 does not have leak, and iOS 5.0+ has leak as Rheeseyb said. And from the stack trace, it seems the leak is from: "- (void)storeCachedResponse:(NSCachedURLResponse *)cachedResponse forRequest:(NSURLRequest...

The leak only happens on iOS 5.0+, not for iOS 4.3 As what I said before, it will cause the leak even I call cachedResponse.data

@steipete Does that mean NSURLCache has on disk cache capability on iOS5 by default?
