reCaptcha not working in iOS6 UIWebView

Hello,I have problems with loading reCAPTCHA with UIWebView component on iOS6.The first time page loads fine. See first screenshot for http://bit.ly/1dG6j4H. But subsequent requests for the same page have captcha image missing. See second screenshot.My controller code is simple: - (void)viewDidLoad { [super viewDidLoad]; [self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://bit.ly/1dG6j4H"]]]; } the second time this controller is show I have broken reCAPTCHA image. Clearing cache with [[NSURLCache sharedURLCache] removeAllCachedResponses]; does not help. Specifying NSURLRequest cache policy does not work too: - (void)viewDidLoad { [super viewDidLoad]; [self.webView loadRequest:[NSURLRequest requestWithURL:[self.reCaptchaURL] cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:60]]; } The problem is specific to iOS 6.0 and iOS 6.1. On iOS 7.0 this code works fine. -- You received this message because you are subscribed to the Google Groups "reCAPTCHA" group.
