CACHE

Is there a way to make web browser's clear there cache before loading a flash website,

I use fire fox and every time i look at my website that i have updated with new content, it does not display the new content, i have to physically clear the cache.

I dont know if this can be done but is there a way in action script to make the browser load up all content and not load of the person own cache. I have haerd that you can con aproxy server's to download the actual content instead of the cached files.

Is it possible and is there an easy way to do this.
