// These are the default delegate methods for request status
// You can use different ones by setting didStartSelector / didFinishSelector / didFailSelector

// When a delegate implements this method, it is expected to process all incoming data itself
// This means that responseData / responseString / downloadDestinationPath etc are ignored
// You can have the request call a different method by setting didReceiveDataSelector
- (void)request:(ASIHTTPRequest *)request didReceiveData:(NSData *)data;

// If a delegate implements one of these, it will be asked to supply credentials when none are available
// The delegate can then either restart the request ([request retryUsingSuppliedCredentials]) once credentials have been set
// or cancel it ([request cancelAuthentication])
