Sned vars to PHP, but in the background

I can PHP no prob, and MySQL. I can even send vars from flash to a PHP page that updates something.

But can I do it in the background?

Like if I wanted to trace where people clicked in flash doc. Occasionally it would send the variables to a PHP page, but not load it into the screen. So the user wouldn’t know?

I’m not going to do anything unethical, I just don’t want to bother the user with loading stupid pages that are just backend things.

I usually load pages with getURL and then just add in the vars.
