Try adding setting the expiry time:
<meta http-equiv="expires" content="Sat, 01 Jan 2001 00:00:00 GMT">
Of course, I'm dealing with images, not HTML content, so META tags are right out. But I added this as a header (using the same mechanism as the previous example) with no luck.
I've had some luck with this combination:
RESPONSE.setHeader('Expires', 'Fri, 05 Jul 2002, 05:00:00 GMT' ); RESPONSE.setHeader('Cache-Control', 'no-store'); RESPONSE.setHeader('Pragma', 'no-cache');
No improvement.
Hmm. You said this was the index_html in a Zclass. Can you have it return an <img> tag instead of the image itself? Then you could do something like this: imageid=randomImage() #returns id of some random image return '<img src="%s/%s" />'%(context.absolute_url(),imageid) No more caching issues. Mark
