Every time the script opens the score.php page, a MySQL table updates itself with the new score.
The problem is, if a user has ever voted, their vote is not always counted if they vote the same score again.
I'm pretty confident this is because the browser is using a cached version of the score.php page, and not requesting the page again.
How can I ensure the browser will always access the link, even if it has already been cached?
Right now the score.php is a blank page. I'm wondering about maybe adding some headers to the page, or something.
