Submit A Form To Two Different URLs

[noxbane]

This probably is a more general programming question and not Wordpress but just in case there was some Wordpress/Genesis related solution, I figured Id post here.

I have a custom form I've created. It needs to submit to a URL of my choosing (or to a Javascript if thats easier). Once submitted my code needs to break apart some of the fields and send some of them to Aweber (to add the lead to their system) and the rest of them to IDX Broker (to add the lead to their system).

What would be my best bet for doing this? I am comfortable with programming. I have heard that submitting it to PHP and using Curl would work, but I'm curious if anyone else has had to deal with this situation before and what they used?
