Demonstrates how to add one or more cookies to an HTTP request. Java

    try {
        System.loadLibrary("chilkat");
    } catch (UnsatisfiedLinkError e) {
      System.err.println("Native code library failed to load.\n" + e);

  public static void main(String argv[])
  {
    boolean success = false;

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

    CkHttp http = new CkHttp();

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

    // Build an HTTP POST request:
    CkHttpRequest req = new CkHttpRequest();
    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.)

    if (success == false) {
        System.out.println(http.lastErrorText());
        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...
        System.out.println(http.lastHeader());
        }
    else {

        }

    // 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.
