Hey!

Try putting the following into a .htaccess file and upload it to your document root:

<FilesMatch "\.(flv|ico|pdf|avi|mov|ppt|doc|mp3|wmv|wav)$">
Header set Cache-Control: "private, pre-check=0, post-check=0, max-age=0"
Header set Expires: 0
Header set Pragma: no-cache
</FilesMatch>

Sorry, I forgot to change the FilesMatch directive. Here's the edited version (for images and Flash):

<FilesMatch "\.(gif|jpg|jpeg|png|swf)$">
Header set Cache-Control: "private, pre-check=0, post-check=0, max-age=0"
Header set Expires: 0
Header set Pragma: no-cache
</FilesMatch>
