1. I have 2 servers
2. Server 2 is protected with digital certificate
3. I have a registration form in server1. When a user register with the site, I need to post the data to server 2 and user should not be prompted for digital certificate.

How can I submit a data to a site with digital certificate protection?

I need to get this done using fsockopen or CURL.I have the pfx file with me.

Please help me.
