// See Global Unlock Sample for sample code.

// Download the contents of a PDF file into the bd object.

    // This will happen if the response status code was 400 or greater,
    // or if the request could not be sent, or if no response was received.
    // 
    // In other words, success will only be YES if bd contains the desired content at the URL (not an error response).
    int statusCode = [http.LastStatus intValue];
    NSLog(@"%@%d",@"Response status: ",statusCode);

    if (statusCode == 0) {
        // There was an error in communications.  
        NSLog(@"%@",http.LastErrorText);
    }
    else {
        // We received a response status code indicating failure.
        // Examine the response body.
        NSLog(@"%@",http.LastResponseBody);
    }

    return;
}

// Save the contents of bd to a file.
// Note: This is only for the sake of this example.
// It's better to call the Download method to download directly to a file.

if (success == NO) {
    NSLog(@"%@",@"Failed to write output file.");
}
