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

Chilkat.HttpRequest req = new Chilkat.HttpRequest();

// This example duplicates the HTTP POST shown at
// http://json.org/JSONRequest.html

// Specifically, the request to be sent looks like this:

// POST /request HTTP/1.1
// Accept: application/jsonrequest
// Content-Encoding: identity
// Content-Length: 72
// Content-Type: application/jsonrequest
// Host: json.penzance.org
// 
// {"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 = false;

// If a Cookie needs to be added..
http.SetRequestHeader("Cookie","JSESSIONID=1234");

string 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.

Chilkat.HttpResponse resp = null;
resp = await http.PostJsonAsync("http://json.penzance.org/request",jsonText);
if (http.LastMethodSuccess != true) {
    Debug.WriteLine(http.LastErrorText);
}
else {
    // Display the JSON response.
    Debug.WriteLine(resp.BodyStr);
