Writing XML with Flash and ASP (Please help!)

So after tons and tons of searching, I have found that you cannot directly write XML files with Flash… but you CAN send variables to a PHP page which, in turn, writes the XML for you.

Problem: my internal server does not have PHP and we are having TONS of problems getting our IIS loaded up with the correct extensions… :sen:

So here is the big question…

Can you do the same sort of thing using asp (write XML through Flash)? And if so, where do I start?
