// 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:
li_Success = loo_Http.CloseAllConnections()
