I need to connect to a remote server via "https" with mutual authentication. This is the code:

        $zendClient = new Zend_Http_Client('https://',
            array(
                'maxredirects'  => 0,
                'strict'        => false,
                'timeout'       => 30,
                'sslcert'       => '.pem',
                'sslpassphrase' => '',
                'adapter'       => 'Zend_Http_Client_Adapter_Curl',
                'curloptions' => array(CURLOPT_SSL_VERIFYPEER => false)
            )
        );

        $zendClient->setHeaders(array(
                                        
                    )
        );

        $zendClient->setRawData('');

        $response = $zendClient->request('POST');

It results in this exception: "Error in cURL request: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure"

If I execute "curl" from shell command line, it connects successfully. This is the command line: curl --cert .pem --cert-type PEM --data-binary '' --header '

<

header value>' --include --insecure --key .key --key-type PEM --pass --show-error --verbose --url

I use: PHP 5.2.11 ZF 1.8.4 libcurl 7.19.6 OpenSSL 0.9.8b

Could you help me please?

Thanks in advance
