no-cache header

[iblis]

I want to have the users cache images to save me some bandwidth, but I still want to force an update on the actuall document..

Is this possible?

Bump...
It would be really great if someone could point me in the right direction..
I'm pulling about 800 megabytes of traffic each day, and it's a bit high :\

well, I know the meta tag to not cache is

<meta name="pragma" content="no-cache">

So the tag to cache might look something like this:

<meta name="pragma" content="cache=all">

you obviously didn't catch my point

i want the images to cache, but not the pages..
thus i cannot use such a code
