The confirmation redirect by default takes place here:
payment/payment_ccend.php
It sets the $request variable and then redirects to it. You can change the redirect by changing this block of code:
Code:
if($weblink==2)
{
func_html_location($request,0);
}
elseif($weblink)
{ print "<a href='".$request."'>";
print "Return to the ".$config["Company"]["company_name"]."</a>";
}
else
func_header_location($request);
I could probably help further if you were more specific in what your trying to accomplish.
