    CkHttp http;

    //  For this initial request, we are not sending cookies.
    //  We are starting a new (cookie) session and saving the cookies we receive.
    http.put_SendCookies(false);

    //  Do a request that establishes and saves cookies in files in the cookie directory.
    const char *html = http.quickGetStr("https://google.com/");

    //  Examine the LastResponseHeader to see the cookies that were received:
    std::cout << http.lastResponseHeader() << "\r\n";
    std::cout << "----------------------------------" << "\r\n";

    //  We can see the following Set-Cookie response header fields:

    //  Set-Cookie: AEC=AVh_V2h-fsL2-****; expires=Mon, 23-Feb-2026 19:15:10 GMT; path=/; domain=.google.com; Secure; HttpOnly; SameSite=lax
    //  Set-Cookie: NID=525=XC_cL****Hn7-WONX; expires=Thu, 26-Feb-2026 19:15:10 GMT; path=/; domain=.google.com; HttpOnly

    //  The following file was created:  c:/temp/cookie_cache/google_com.xml

    //  Examine the cookies received in the above request.
    std::cout << http.getCookieXml("google.com") << "\r\n";
    std::cout << "----------------------------------" << "\r\n";

    //  Sample output.

    //  <?xml version="1.0" encoding="utf-8"?>
    //  <cookies>
    //      <cookie key=".google.com,/,AEC" v="0" expire="Mon, 23-Feb-2026 19:05:20 GMT" secure="yes">

    //      </cookie>
    //  </cookies>

    //  -------------------------------------------------------------------------------------------
    //  Let's say we want to continue with the session at some later time with a new HTTP object.
    //  One way to do it is to simply set the same cookie properties:
    CkHttp httpB;

    httpB.put_SaveCookies(true);
    httpB.put_CookieDir("c:/temp/cookie_cache");
    httpB.put_SendCookies(true);

    //  The cookies from the cache are sent.
    html = httpB.quickGetStr("https://google.com/");

    //  Examine the LastHeader to see the contents of the Cookie header field.
    std::cout << httpB.lastHeader() << "\r\n";
    std::cout << "----------------------------------" << "\r\n";

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

    CkHttp httpC;

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

    CkStringBuilder sbCookiesXml;
    success = sbCookiesXml.LoadFile("c:/temp/cookie_cache/google_com.xml","utf-8");
    if (success == false) {
        std::cout << sbCookiesXml.lastErrorText() << "\r\n";
        return;
    }

    success = httpC.SetCookieXml("google.com",sbCookiesXml.getAsString());
    if (success == false) {
        std::cout << httpC.lastErrorText() << "\r\n";
        return;
    }

    html = httpC.quickGetStr("https://google.com/");

    //  Examine the LastHeader to see the contents of the Cookie header field.
    std::cout << httpC.lastHeader() << "\r\n";
