Server Storing Flash Variables

Hi.
I have a flash game that is sort of a test, that tracks users scores and other stuff. I am wondering what would be the best way to send and store these varibles in a file on my server, where flash could then read that file and display some statistical data, because I need to see how people are doing on the test.

What would be the best way to do this? Is it storing all the variables in an XML file and if so how would that be done, I know a little XML, but what way would multiple users send variables from flash to the server’s XML file?

Can anyone help me?:slight_smile:
