ActionScript 3.0 :: Send Two Fields To An Asp.net Validate Page?

I need to send two fields to an asp.net validate page. It's a login, and the client is handling all errors on their end. So just need to pass them the two variables (username and password) and send the user to the asp page.So I gather it's going to look something like this:

Code:
var variables:URLVariables = new URLVariables();
var varSend:URLRequest = new URLRequest("valildate.asp");
var varLoader:URLLoader = new URLLoader();[code]...........
