    // To use HTTP Digest Authentication:
    http.put_Login("myLogin");
    http.put_Password("myPassword");
    http.put_DigestAuth(true);

    // If you would like to see the HTTP session log to see how 
    // HTTP digest authentication worked.

    // Run the test using this URL with the credentials above.  
    // (Works while httpbin.org keeps the test endpoint available.)
    const char *jsonResponse = http.quickGetStr("https://httpbin.org/digest-auth/auth/myLogin/myPassword");
    if (http.get_LastMethodSuccess() == false) {
        std::cout << http.lastErrorText() << "\r\n";

    }

    std::cout << "Response status code: " << http.get_LastStatus() << "\r\n";

    std::cout << jsonResponse << "\r\n";

    // Output:

    // Response status code: 200
    // {
    //   "authenticated": true, 
    //   "user": "myLogin"
