Demonstrates how to call the CloseAllConnections method. C#

bool success = false;

Chilkat.Http http = new Chilkat.Http();

//  Demonstrate 
string url = "https://finnhub.io/api/v1/quote?symbol={$symbol}&token={$api_key}";

//  When the request is sent, the {$symbol} is replaced with "MSFT"
//  and the {$api_key} is replaced with "1234567890ABCDEF"
http.SetUrlVar("symbol","MSFT");
http.SetUrlVar("api_key","1234567890ABCDEF");

Chilkat.StringBuilder sbJson = new Chilkat.StringBuilder();
success = http.QuickGetSb(url,sbJson);
if (success == false) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

int statusCode = http.LastStatus;
Debug.WriteLine(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) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

Debug.WriteLine("Success.");
