// Needs #include <CkHttp.h>

    CkString strOut;

    CkHttp http;

    bool success;

    //  Any string unlocks the component for the 1st 30-days.
    success = http.UnlockComponent("Anything for 30-day trial");
    if (success != true) {
        strOut.append(http.lastErrorText());
        strOut.append("\r\n");
        SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
        return;
    }

    //  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:
    http.put_CookieDir("/cookieDir");
    http.put_SaveCookies(true);

    //  Any methods that do a GET, POST, etc. will save cookies
    //  to the CookieDir:
    const char * html;
    html = http.quickGetStr("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.
    http.put_SendCookies(true);

    //  If another HTTP request is sent, the cookies should
    //  be added:
    html = http.quickGetStr("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.
    strOut.append("--- LastHeader ---");
    strOut.append("\r\n");
    strOut.append(http.lastHeader());
    strOut.append("\r\n");


    SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
