Hi

I am using the php extension - php_curl.dll library.

I have an option within my web application, where I accept the Remote Host
URL or IP address to connect, from the user and use curl to connect and
process data. If there is no proxy server then the connection and the
data exchange goes through fine.

When there is an intermediate ISA Proxy Server to connect to the internet,
the user has to specify the Proxy Server address, windows login info.

The code I use when there is a proxy server is as follows:-

            $ch = curl_init();
            curl_setopt($ch, CURLOPT_URL, $url);
            curl_setopt($ch, CURLOPT_HEADER, false); //if you
want the header
            curl_setopt($ch, CURLOPT_RETURNTRANSFER , true); // return
the results as a string return value
            curl_setopt($ch, CURLOPT_POST , true);
            if (strlen(trim($proxy))>0)
            {
                  $auth =
$_REQUEST[wDomain]."\\".$_REQUEST[uWindowsAl].":".$_REQUEST[uWindowsPa];
                  curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL,1);
                  curl_setopt ($ch,CURLOPT_PROXYTYPE, CURLPROXY_HTTP);
                  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
                  curl_setopt($ch, CURLOPT_PROXY,$proxy);
                  curl_setopt($ch,CURLOPT_ProxyAUTH,CURLAUTH_NTLM);
                  curl_setopt($ch, CURLOPT_PROXYUSERPWD,$auth);
            }
            curl_setopt($ch, CURLOPT_POSTFIELDS,
"req=".urlencode($buf)."&");
            $body = curl_exec($ch);
            $http=curl_getinfo($ch);
            $errDesc = curl_error($ch);
            $errNo = curl_errno($ch);
            curl_close($ch);

The out I am receiving is

I hope the above information is sufficient to determine the problem.

There's a huge lack of details in your mail, but I would guess that your
request failed already on the CONNECT and you're not checking the
CURLINFO_HTTP_CONNECTCODE.
