Flash Cache Problem

Hello,

I have this problem where when I update my flash movies and reupload them to my server, my browser doesn’t see the new flash movie. Instead, it shows the old one.

Refreshing doesn’t work. Quitting doesn’t work either. I learned I can fix it by emptying my browsers cache. But I don’t want all my visitors to have to do the same thing when they come.

How can I get my browers, and my visitors browsers to always see the updated content (I update a lot)? I was told briefely about DUMMY VARIABLES, but I’m not sure what they are or where I would put them.

Thanks for your help,
Daniel
