CB connect -> How to redirect user to specific page after succesful login

Hi,

I use CB 1.9 + Joomla 2.5

I have CB connect to let users login with FB, T and G+.

I am making a launch page outside of joomla system. People can register and I will use the CB plugin in my php code to let people login or register with their social account.

The problem is the redirection. How can I redirect user to a specific page of my server?

Any one can help?

Thank you.
