I would try operating the origin website on SSL, (or try running Squid as an HTTP -> HTTPS bridge - but probably too complicated). I believe that if content is delivered by SSL, it is not cached by the browser in a way that is readable... Just my 2c worth...

Why do you want to? If it's to stop people from being able to copy the files, you'll fail. Otherwise... > ( ie: meta tag swap ..

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. ****************************************************************** Think Before You Print ================================================================== The HENLEY College ------------------------------------------------------------------ This message and any files transmitted with it is intended for the addressee only and may contain information that is confidential and/or legally privileged.
