Perl

Example: Http.CloseAllConnections method

See more HTTP Examples

Demonstrates how to call the CloseAllConnections method. Perl

use chilkat();

$success = 0;

$http = chilkat::CkHttp->new();

# Demonstrate 
$url = "https://finnhub.io/api/v1/quote?symbol={$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");

$sbJson = chilkat::CkStringBuilder->new();
$success = $http->QuickGetSb($url,$sbJson);
if ($success == 0) {
    print $http->lastErrorText() . "\r\n";
    exit;
}

$statusCode = $http->get_LastStatus();
print $http->lastResponseHeader() . "\r\n";

# 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 == 0) {
    print $http->lastErrorText() . "\r\n";
    exit;
}

print "Success." . "\r\n";
