Data Won't Refresh? Cache?

1

I have a piece of flash that pulls data from a mySQL database via PHP.

Problem:
If I load the page, then change the data in the SQL database, then refresh the page, the data does not update?

How can I make sure that the data is pulled from the database everytime the page is loaded?

Yes, you can make it even more powerfull by having it get a random number between 1 and 10000 (or something), instead of the timer.
