submitting a form to multiple places!!!

Hi All, I have a problem that I hope you can help me with. I'm using a third party shopping cart solution which is quite frankly naff. They bundle some autoresponders with it. Unfortunately the autoresponders do not work!. I want to find a temporary solution to this. The easiest way would be to allow a form to be submitted to more than one place! Basically I would lke to have an intermediate php page that will submit the details (submitted to it) to two other pages and then follow the response of one of those other pages (the primary page). That way I can insert a different autoresponder handling system into the submission process but continue to use the shopping carts pages for the time being. Any suggestions? Henry
