    // See Global Unlock Sample for sample code.

    http = CkHttp_Create();

    // To save cookies to XML files (per domain) in a specific
    // directory, set the CookieDir property (the directory must
    // already exist and be writeable by the caller).  Also,
    // set the SaveCookies property:
    CkHttp_putCookieDir(http,"/cookieDir");
    CkHttp_putSaveCookies(http,TRUE);

    // Any methods that do a GET, POST, etc. will save cookies
    // to the CookieDir:

    html = CkHttp_quickGetStr(http,"https://www.paypal.com/");

    // After running this code, a "paypal_com.xml" file should appear
    // in /cookieDir.

    // It's content will look something like this:

    // <cookies>
    //     <cookie key=".paypal.com,/" v="0" secure="yes">
    //         <navcmd>_home-general</navcmd>
    //         <HttpOnly />
    //         <cwrClyrK4LoCV1fydGbAxiNL6iG>9cz...</cwrClyrK4LoCV1fydGbAxiNL6iG>
    //     </cookie>
    // </cookies>

    // To cause cached cookies to be sent with 
    // subsequent HTTP requests, set the SendCookies
    // property = TRUE.
    CkHttp_putSendCookies(http,TRUE);

    // If another HTTP request is sent, the cookies should
    // be added:
    html = CkHttp_quickGetStr(http,"https://www.paypal.com/");

    // Check the LastHeader property to see the MIME header
    // of the last HTTP request sent.
    // The "Cookie" header field should be present.
    printf("--- LastHeader ---\n");
    printf("%s\n",CkHttp_lastHeader(http));
