Firefox browser cache issue

[stax76]

I host a file with a simple filename, I often replace this file with a new version, the filename don't change. Often when people download this file, Firefox takes it from the browser cache so people download a old version, is there anything I can do against this? IE don't has this problem. I'm running a Drupal site btw. This is the problematic page (http://planetdvb.net/staxrip/download).

Edit: I've solved it using different filenames to be sure.

You may want to look at these:
HTTP Caching in Mozilla (http://www.mozilla.org/projects/netlib/http/http-caching-faq.html)
RFC2616 13.2 Expiration Model (http://www.rfc.net/rfc2616.html#s13.2)
It sounds like you may be able to add some sort expiration response header to fix the problem.
