Hi,
 
I am facing some issues regarding the client certificate for php 5.2.x running on IIS 6. The same code works on linux machine running apache/php
 
                                $applicationPath=realpath(dirname(__FILE__));
                                $url = "https://<siteurl> ";
        $clientcert = $applicationPath."/clientcertificate.pem";
        $keyfile = $applicationPath."/userkey.pem";
        $challenge = "XXXXXXXXXXX";
                                echo $clientcert.'<br>';
                                echo $keyfile.'<br>';
                                echo $challenge;
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_VERBOSE, 1);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
        curl_setopt($ch, CURLOPT_FAILONERROR, 1);
        curl_setopt($ch, CURLOPT_SSLCERT, $clientcert);
        curl_setopt($ch, CURLOPT_SSLCERTPASSWD, $challenge);
        //curl_setopt($ch, CURLOPT_SSLKEYTYPE, 'PEM');
        //curl_setopt($ch, CURLOPT_SSLKEY, $keyfile);
        $ret = curl_exec($ch);
                                echo '<br /><br /><b>Xml Output</b>';
                                echo '<br /><br />';
                                echo htmlentities($ret).'<br /><br />';
                                if (curl_error($ch))
                                                printf("Error %s: %s", curl_errno($ch), curl_error($ch));
                                curl_close($ch);
 
This is the response I get from Linux machine running php
 
Xml Output

<?xml version="1.0" encoding="UTF-8"?> <list> </list>
 
 
On Windows server the code fails for some reason and I get this error
 
Error 52: Empty reply from server*
 
What configuration changes do I need to make so that code runs on windows server.
 
Thanks,
Kailash
