Pass form variables on to second postback...asp.net
<p>Is it possible to postback to the server, perform a function, and then continue that postback on to an external place? (ie, to a payment system)</p>

<p>(the scenario is clicking a button to place an order, mark it as sent, then send them off to the payment page (there are form variables that needs to be sent to the payment screen as well))</p>
