[Plugin: WP Super Cache] How would a page like this be cached?

Hi, I have WP Super Cache on my site which is currently under development. I am going to have a page that uses PHP to get the page contents from a database. In order to know what to get, it will be using the PHP $_GET function. But the URLs will be rewritten behind the scenes to look like /page/1, instead of /page.php?id=1. So my question is, will WP Super Cache cache the dynamically generated pages page/1, page/2, etc., or would it only cache page.php once?
