    Log.i(TAG, http.lastResponseHeader());

    //  The response header contains this:

    //  Date: Tue, 19 Aug 2025 12:18:56 GMT
    //  Content-Type: application/json; charset=utf-8
    //  Transfer-Encoding: chunked
    //  Connection: keep-alive
    //  Content-Encoding: gzip

    //  The "Connection: keep-alive" header ensures the server keeps the connection open for subsequent requests.
    //  If the server responds with a "Connection: close" header, it indicates the connection will be closed after the response. 
    //  Consequently, Chilkat will also close the connection, requiring a new one to be established for any subsequent requests to the same server.

    //  If your application uses the same HTTP object instance to send requests to a different server, a new connection will be established with that server.
    //  Existing connections remain open, with Chilkat maintaining up to 10 open connections. 
    //  If all 10 connections are in use, Chilkat will close the least recently used connection to connect to a new server.

    //  Your application can explicitly close all open connections like this:
    success = http.CloseAllConnections();
    if (success == false) {
        Log.i(TAG, http.lastErrorText());
