I was looking at the cacheability of my website in zope, and saw that the misc_/OFSP/*.gif images (as in the icon objects) are NOT cacheable because they don't return *any* date info. If they *at least* returned a Last Modified, they'd be cacheable. My browser (Netscape 4.74) happily cashes these images.
It is not clear, why a "Last Modified" header should be a precondition for caching. I would expect it is only necessary, if you told your browser (or other cache) to verify freshness for each request. If the browser has a "Last Modified", it sends an "If-Modified-Since" header and get a 304 response, if not. Dieter
