    // The FollowRedirects property controls whether redirects
    // are automatically followed.  The default behavior is to
    // automatically follow redirects.

    // Explicitly set FollowRedirects so that redirects are NOT automatically taken:
    http.FollowRedirects = false;

    var resp = new chilkat.HttpResponse();
    success = http.HttpNoBody("GET","http://yandex.ru/",resp);

    console.log("HTTP Response Status: " + status);

    // The FinalRedirectUrl property will contain the redirect URL
    // If FollowRedirects was equal to true, then all of the 
    // intermediate redirects (if any) would be followed until
    // there were no more redirects.  However, because 
    // FollowRedirects is not true, FinalRedirectUrl contains
    // the next redirect URL.

    var loopCount = 0;

    while ((status == 302)) {

        console.log("Redirect URL: " + http.FinalRedirectUrl);

        var nextUrl = http.FinalRedirectUrl;

        console.log("HTTP Response Status: " + status);

        // For safety, prevent infinite loops by
        // keeping a loopCount and only allows following a max 
        // of 10 redirects:
        loopCount = loopCount+1;
