# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# This example connects to a REST server through an HTTP proxy.
# It will connect to the Amazon AWS service for this example.
$rest = chilkat::CkRest->new();
$socket = chilkat::CkSocket->new();

# Set the HTTP proxy domain or IP address, and port.
$socket->put_HttpProxyHostname("192.168.1.100");
$socket->put_HttpProxyPort(8088);

# We want to tell the socket object that we're doing HTTP over the proxy connection.
# This is because an HTTP proxy used for other protocols (IMAP, SMTP, SSH, FTP, etc.) 
# can require some internal differences in behavior (i.e. how we do things).
$socket->put_HttpProxyForHttp(1);

# Other properties exist for specifying a proxy login, password, and authentication method (such as NTLM),
# but these are not used in this example.

# Connect through the HTTP proxy to the Amazon AWS server for the S3 service.

    print "Connect Failure Error Code: " . $socket->get_ConnectFailReason() . "\r\n";
    print $socket->lastErrorText() . "\r\n";

# Use the proxied TLS connection:
$success = $rest->UseConnection($socket,1);
if ($success != 1) {
    print $rest->lastErrorText() . "\r\n";
    exit;
}

# Provide AWS credentials for the REST call.

$authAws->put_SecretKey("AWS_SECRET_KEY");

# List all buckets for the account...

    exit;
}

# Show the full XML returned.
print $xml->getXml() . "\r\n";

# Iterate over the buckets, showing each bucket name.
