// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

CkoRest *rest = [[CkoRest alloc] init];

// We're going to check https://authenticationtest.com/HTTPAuth/
BOOL bTls = YES;
int port = 443;
BOOL bAutoReconnect = YES;
BOOL success = [rest Connect: @"authenticationtest.com" port: [NSNumber numberWithInt: port] tls: bTls autoReconnect: bAutoReconnect];
if (success != YES) {
    NSLog(@"%@",rest.LastErrorText);
    return;
}

// Send a GET request
NSString *responseText = [rest FullRequestNoBody: @"GET" uriPath: @"/HTTPAuth/"];
if (rest.LastMethodSuccess != YES) {
    NSLog(@"%@",rest.LastErrorText);
    return;
}

// The start line of an HTTP response, called the status line, contains the following information:
// 
//     The protocol version, usually HTTP/1.1.
//     A status code, indicating success or failure of the request. Common status codes are 200, 404, or 302
//     A status text. A brief, purely informational, textual description of the status code to help a human understand the HTTP message.
// 
// A typical status line looks like: HTTP/1.1 404 Not Found.

// The ResponseStatusCode property contains the integer response code:
NSLog(@"%@%d",@"Response status code = ",[rest.ResponseStatusCode intValue]);

// The ResponseStatusText property contains the text (if any) that follows the status code on the status line.
NSLog(@"%@%@",@"Response status text = ",rest.ResponseStatusText);

// In this case, the sample output is:
// 
// Response status code = 401
// Response status text = Unauthorized
