Josh, Thank you. Problem is that I am using a test account from http://vcl.ncsu.edu/ and I can't disable SSL, but as far as I know you are using http requests not https:
$context = stream_context_create( array( '*http*' => array( 'method' => "POST", 'header' => $header, 'content' => $request ) ) ); I tried XML standard queries but I receive permission denied error, I don't know if the problem is with (http,https) or with my queries. I guess they have some more information in their request. By the way, do you know how can I know what this function sends to server : file_get_contents(self::VCLHOST.$location, false, $context) Best Regards Mani On Fri, Dec 2, 2011 at 9:04 AM, Josh Thompson <josh_thomp...@ncsu.edu>wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Mani, > > The frontend code is not using Cookie for anything when the XMLRPC API is > used. > > I'm not actually sure about the XML part.
