    // Content-Type: application/json; charset=utf-8
    // Transfer-Encoding: chunked
    // Connection: keep-alive

    // 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:
