Here's a work-around to get HTTP response code, but with sending just one request to each URL:-

BOOL isLoad;
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType{
    NSLog(@"Requesting: %@ - %d - %@", request.URL.absoluteString, navigationType, request.URL.host);
    if (navigationType != UIWebViewNavigationTypeOther) {
        //Store last selected URL
        self.loadedURL = request.URL.absoluteString;
    }
    if (!isLoad && [request.URL.absoluteString isEqualToString:loadedURL]) {
        [NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
            if (connectionError || ([response respondsToSelector:@selector(statusCode)] && [((NSHTTPURLResponse *)response) statusCode] != 200 && [((NSHTTPURLResponse *)response) statusCode] != 302)) {
                //Show error message
                [self showErrorMessage];
            }else {
                isLoad = YES;
                [_wbView loadData:data MIMEType:[response MIMEType]
                 textEncodingName:[response textEncodingName]
                          baseURL:[response URL]];
            }
        }];
        return NO;
    }
    isLoad = NO;
    return YES;
}
