Sending information to a script on another host....

Hello, I am trying to make a script that automates domain name registration. What I need my script to do is send information to a script that opensrs runs to activate a pending order. But I don't want to redirect the user there. I only want to send information there and then take the user to a friendly pretty place. I have some reason to believe has to do with cURL, but not sure. I hope you understand what I am saying. Thanks Brandon
