CkoHttp *http = [[CkoHttp alloc] init];
NSString *url = @"https://www.example.com/";

// The GetHead method is deprecated:

if (http.LastMethodSuccess == NO) {
    NSLog(@"%@",http.LastErrorText);
    return;
}

NSLog(@"%d",[resp1.StatusCode intValue]);

// ------------------------------------------------------------------------
// Do the equivalent using HttpNoBody.
// Your application creates a new, empty response object which is passed 
// in the last argument and filled with the HTTP response upon success.

CkoHttpResponse *resp2 = [[CkoHttpResponse alloc] init];
BOOL success = [http HttpNoBody: @"HEAD" url: url response: resp2];
if (success == NO) {
    NSLog(@"%@",http.LastErrorText);
