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

CkoHttpRequest *req = [[CkoHttpRequest alloc] init];
CkoHttp *http = [[CkoHttp alloc] init];

// The PUT request to be sent will look like this:

// PUT /request HTTP/1.1
// Content-Type: application/jsonrequest
// Cookie: JSESSIONID=1234
// Content-Encoding: identity
// Host: json.penzance.org
// Accept: application/jsonrequest
// Accept-Encoding:
// Content-Length: 72
// 
// {"user":"doctoravatar@penzance.com","forecast":7,"t":"vlIj","zip":94089}

// First, remove default header fields that would be automatically
// sent.  (These headers are harmless, and shouldn't need to 
// be suppressed, but just in case...)
http.AcceptCharset = @"";
http.UserAgent = @"";
http.AcceptLanguage = @"";

// Suppress the Accept-Encoding header by disallowing 
// a gzip response:
http.AllowGzip = NO;

// If a Cookie needs to be added...
[http SetRequestHeader: @"Cookie" value: @"JSESSIONID=1234"];

// Add the Content-Encoding: identity header.
[http SetRequestHeader: @"Content-Encoding" value: @"identity"];

// Modify the default "Accept" header:
http.Accept = @"application/jsonrequest";

NSString *jsonText = @"{\"user\":\"doctoravatar@penzance.com\",\"forecast\":7,\"t\":\"vlIj\",\"zip\":94089}";

// To use SSL/TLS, simply use "https://" in the URL.

// IMPORTANT: Make sure to change the URL, JSON text,
// and other data items to your own values.  The URL used
// in this example will not actually work.

NSString *responseBody = [http PutText: @"http://json.penzance.org/request" textData: jsonText charset: @"utf-8" contentType: @"application/jsonrequest" md5: NO gzip: NO];
if (http.LastMethodSuccess != YES) {
    NSLog(@"%@",http.LastErrorText);
}
else {
    // Display the JSON response.
    NSLog(@"%@",responseBody);
