    CkHttp http;

    // The Cookie header field has this format:
    // Cookie: name1=value1 [; name2=value2] ...

    // Build an HTTP POST request:
    CkHttpRequest req;
    req.SetFromUrl("http://www.chilkatsoft.com/echoPost.asp");
    req.put_HttpVerb("POST");

    req.AddParam("param1","value1");
    req.AddParam("param2","value2");

    // To add cookies to any HTTP request sent by a Chilkat HTTP method
    // that uses an HTTP request object, add the cookies to the
    // request object by calling AddHeader.  

    // Add two cookies:
    req.AddHeader("Cookie","user=\"mary\"; city=\"Chicago\"");

    // Send the HTTP POST.  
    // (The cookies are sent as part of the HTTP header.)

    CkHttpResponse *resp = 0;
    const char *domain = "www.chilkatsoft.com";
    int port = 80;
    bool ssl = false;
    resp = http.SynchronousRequest(domain,port,ssl,req);
    if (http.get_LastMethodSuccess() != true) {
        std::cout << http.lastErrorText() << "\r\n";
        return;
    }

    // Display the HTML body of the response.
    if (resp->get_StatusCode() == 200) {
        // Show the last HTTP request header sent, which should include
        // our cookies...
        std::cout << http.lastHeader() << "\r\n";
    }
    else {
        std::cout << "HTTP Response Status = " << resp->get_StatusCode() << "\r\n";
    }

    delete resp;

    std::cout << "---------------------" << "\r\n";

    // Some Chilkat HTTP methods do not use an HTTP request object. 
    // For these methods, such as for QuickGetStr, cookies (or any HTTP request header) 
    // are added by calling SetRequestHeader.  
    http.SetRequestHeader("Cookie","user=\"mary\"; city=\"Chicago\"");

    const char *html = http.quickGetStr("http://www.w3.org/");
    if (http.get_LastMethodSuccess() != true) {
        std::cout << http.lastErrorText() << "\r\n";
    }
    else {
        // Show the last HTTP request header sent, which should include
        // our cookies...
