Ok, I have looked into this a bit further.
Currently, actual discussion pages are sent with:
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
On several discussions in Usenet (found via deja.com) I found recommendations/comments that these (META HTTP-EQUIV) don't work well with (some?) caching proxy servers, as they don't try looking into the document itself.
It is repeatedly recommended to use real HTTP headers (for which the above are only a substitute is the page-writer has no control over the server that sends the headers) instead. These would have to be configured in the webserver I believe..
While I'm not a real HTTP expert, I believe the headers used should be:
Expires: 0
Cache-Control: post-check=0, pre-check=0
Pragma: no-cache
