Dear Magnolians
We have been faced with this rather serious problem with several
Magnolia sites: Content is not being refreshed unless you clear the
browser cache.
To illustrate things, I ran the following test below today. Could
anyone tell me what I have to do that Magnolia does NOT return a 304
"Not modified" header for modified pages?! I cannot send out mails to
all internet users telling them to clear their cache...
Thanks a bunch.
