Post a form to a popup and leave the original page alone

hi guys.

is it possible to post a form to a new popup and leave the original form alone.

let’s say i’ve got this

<form name="test" action="process.php" method="POST" >
<input type="text" name="input1" value="blabla" />
<textarea name="input2"></textarea>
<input type="submit /><input type="button" onClick="OpenNewWindow();" />

and i want the form elements to be posted to the process2.php in a new window but still want the user to be able to click submit ones process2.php is done.

Is that at all possible and if so how?
