    // Specifiy a session log file so we can see the exact request/response
    http.put_SessionLogFilename("c:/aaworkarea/sessionLog.txt");

    // Perhaps add a custom header or two..
    http.SetRequestHeader("x-exz-date","20201012T235046Z");

        return;
    }

    // The GET request that is sent looks like this.
    // The Accept and Accept-Encoding headers are automatically added by default.

    // 	GET /someting?param1=123&param2=abc HTTP/1.1
    // 	Host: www.example.com
    // 	Accept: */*
    // 	Accept-Encoding: gzip
    // 	x-exz-date: 20201012T235046Z
    // 	x-exz-id: 1234

    // Get the response status
    int statusCode = resp.get_StatusCode();
    std::cout << "Response status: " << statusCode << "\r\n";

    // Get the response body
    std::cout << resp.bodyStr() << "\r\n";

    // -------------------------------------------------------------
    // Let's say we want to send a DELETE request, and we only want to accept an application/json response,
    // and we don't want gzipped responses...

    // First remove the previously specified custom headers.
    http.ClearHeaders();

    // Indicate we only accept application/json non-gzipped responses.
    http.put_Accept("application/json");
    http.put_AllowGzip(false);

    // Send a DELETE request to https://www.example.com/deleteSomething
    url = "https://www.example.com/deleteSomething";
    success = http.HttpNoBody("DELETE",url,resp);
    if (success == false) {
        std::cout << http.lastErrorText() << "\r\n";
        return;
    }

    // The DELETE request that is sent looks like this.
    // The empty Accept-Encoding header value means we only want non-compressed responses.

    // 	DELETE /deleteSomething HTTP/1.1
    // 	Host: www.example.com
    // 	Accept: application/json
    // 	Accept-Encoding: 

    // Get the response status
    statusCode = resp.get_StatusCode();
    std::cout << "Response status: " << statusCode << "\r\n";

    // Get the response body
    std::cout << resp.bodyStr() << "\r\n";
