    // Let's say we want to continue with the session at some later time with a new HTTP object.

    // Examine the LastHeader to see the contents of the Cookie header field.
    System.out.println(httpB.lastHeader());
    System.out.println("----------------------------------");

    // -------------------------------------------------------------------------------------------
    // Another way to do it is to explicitly load the cookies from XML
    // and set the cookies for the particular domain.

    CkHttp httpC = new CkHttp();

    httpC.put_SaveCookies(true);
    // Do not save cookies to files, just keep them in memory.
