Trouble with no-cache in ie7

[SarK0Y]

Good time to All, Amigos!

i wonder - have necessity to forbid saving swf and applets into cache, for it, did try following tags:
<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Cache-Control" content="no-cache">
<meta http-equiv="Expires" content="-1">

no one doesn't work.
-----------------------------------------
Thanks in Advance.

These are HTML HTTP-equivalent tags, and they go on HTML pages. You would have to put these HTML tags onto non-HTML files like swf and flv files, which is impossible -- If you did this, then those files would no longer be valid.

Instead, you need to configure your server to send the 'real' HTTP server response headers, such as Cache-Control, Expires, and Pragma. How you do this depends on your server type (e.g. Apache or IIS) and other things, such as whether you use scripts to serve your media files.

Thanks for reply, jdMorgan.
hmmmm... if i haven't an access to server, then what to do?

[jdMorgan]

If you don't use a script to serve content, and don't have any server control access, then there is nothing you can do. You need a better server.

hmmm.... follow idea, cache must work so: each file on the server has hashsum, browser checks file's hashsum out before downloading it but practice doesn't use this method:( why?
