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: http://www.zope.org/Members/johanc/EasySystem/EasyImage/index_html Regards, Johan Carlsson
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>
