Why do you want to? If it's to stop people from being able to copy
the files, you'll fail. Otherwise...

Squid can only remove headers, to the best of my knowledge. To add
them, you need to do it on the origin server. You say you're using
squid as a reverse proxy, so you'll need to configure your web
server to set the appropriate HTTP headers when serving .flv files;
you can't use HTML <meta> tags, they need to be real HTTP headers.
(I'm guessing .flv files don't have anywhere to put such things, but
it seems like a fairly safe guess.)

Even with this done, it's posible MSIE will still save the files as
part of how it operates internally. I'm not certain about that,
though.
