Re: Cache-Control not working

23 Aug 2001

      So, I figured it out (it not a bad idea to sleep ones in a while).

I was hiting the refresh button which makes the browser send
a If-Modified-Since request. When I use a link to refresh the
page it behaves correctly. Even for images, which was my
initial target for browser caching.

I have put my work on zope.org, for anyone interested:

Hi all, 
Has anyone be able to use Cache-Control from Zope?
I've tried both of the following headers (the later one for IE5.5)
but I a new DateTime each time.
Maybe it's just my browsers (IE5.5 and Netscape® Communicator 4.75)
DTML-Method:
<dtml-call "RESPONSE.addHeader('Cache-Control','max-age=100000')">
<dtml-call "RESPONSE.addHeader('Cache-Control','post-check=100000, pre-check=50000')">
<html><body>
<pre>
<dtml-var "_.DateTime()">
</pre>
</body></html>
Catched output from ZPublisher.Publish.py (publish):
