i've followed the thread with interest, and test some of the solutions.  but,
ie doesn't really honor the headers, me think.  or maybe i'm too dense!

what i did:
<dtml-call "RESPONSE.setHeader('expires',(_.DateTime() + .001).toZone('GMT').strftime('%a, %d %b %Y %H:%M:%S GMT'))">
<dtml-call "RESPONSE.setHeader('cache-control','no-cache')">
<dtml-call "RESPONSE.setHeader('Last-Modified',bobobase_modification_time().toZone('GMT').strftime('%a, %d %b %Y %H:%M:%S GMT') )">

in the very top of my standard_html_header

netscape rendered great, while ie will give me intermittent result.  most of
the time, it spits out old pages, which is a nono since this is a news site!

i'm not following you here.  (i'm  a newbie.   sometimes, it's a great excuse
;))

i thought of it as a cache to all dynamic calls, so i got a static page, with
no need for processing dynamic objects (e.g date time, getting objects from
other objects, etc)  correct me if  i'm wrong

maybe neli@zopers.org(cachepool author) can chime in here.

i'll try and look into this again.  will also look into squid.
