Is it possible to have an ASP page submit information to a script on another website (as if I had filled in a form on that website myself) but not have feed the script's outcome back to the browser?

What I'm trying to do is create a form that submits a message to a script on ICQ's site (their script then sends me an icq message) but instead of sending the standard ICQ reply back to the browser I would like to send my own (iqnoring whatever ICQ send back). Is this possible?

I've thought of compililing the necessary url and query string like:

Code:
http://wwp.mirabilis.com/scripts/WWPMsg.dll?subject=Message+Subject&to=31422892&from=Matthew+Ralston&[email protected]&body=Message+Text
But again, how do I send this without redirecting the browser there?
