Determine if download object is an HTML redirection page - stop downloading before the page loads

When I try to download a file with AFDownloadRequestOperation from a URL, the Wi-fi router turns off internet connection and redirects me to an authorization page. The download process does not stop during this redirection and I get an HTML redirection page instead of a file that was supposed to be downloaded. It tells me that it's okay and that the file is downloaded.

How can I determine that a download object is an html redirection page and stop downloading it before I get that page?

NSURLConnection (the underlying framework class) does support this sort of notificationvia:

- (NSURLRequest *)connection:(NSURLConnection *)connection willSendRequest:(NSURLRequest *)request redirectResponse:(NSURLResponse *)response;

=> AFNetworking exposes this via block that is to be called when a redirect happens:

@property (readwrite, nonatomic, copy) AFURLConnectionOperationRedirectResponseBlock redirectResponse;
