Demonstrates how to connect through an HTTP proxy server.

Chilkat Perl Downloads

Perl Module for Windows, Linux, MAC OS X, Solaris, and FreeBSD

use chilkat();

$socket = new chilkat::CkSocket();

$success = $socket->UnlockComponent("Anything for 30-day trial");
if ($success != 1) {
    print $socket->lastErrorText() . "\r\n";
    exit;
}

#  To connect through an HTTP proxy, set the HttpProxyHostname
#  and HttpProxyPort properties to the hostname (or IP address)
#  and port of the HTTP proxy.  Typical port numbers used by
#  HTTP proxy servers are 3128 and 8080.
$socket->put_HttpProxyHostname("www.my-http-proxy.com");
$socket->put_HttpProxyPort(3128);

#  Important:  Your HTTP proxy server must allow non-HTTP
#  traffic to pass.  Otherwise this does not work.

#  Connect (via the HTTP proxy) to port 5555 of 192.168.1.108.
#  hostname may be a domain name or IP address.
$hostname = "192.168.1.108";
$ssl = 0;
$maxWaitMillisec = 20000;
$success = $socket->Connect($hostname,5555,$ssl,$maxWaitMillisec);
if ($success != 1) {
    print $socket->lastErrorText() . "\r\n";
    exit;
}

#  Set maximum timeouts for reading an writing (in millisec)
$socket->put_MaxReadIdleMs(10000);
$socket->put_MaxSendIdleMs(10000);

#  The ficticious server (in this example) is going to send a "Hello World!"
#  message.  Read it:
$receivedMsg = $socket->receiveString();
if ($socket->get_LastMethodSuccess() != 1) {
    print $socket->lastErrorText() . "\r\n";
    exit;
}

#  Close the connection with the server
#  Wait a max of 20 seconds (20000 millsec)
$success = $socket->Close(20000);

print $receivedMsg . "\r\n";
