[Zope] Re: Cache-Control not working

Thu, 23 Aug 2001 10:43:53 +0200

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:
