Hi,all:
I need to set an http header to jsp so that
whenever a user request that page(like have some
action in other page then redirect back to it),
it will refresh(reload).
What we do right now is use:
<META HTTP-EQUIV="expires" CONTENT="0">.
but it comes with problem when a proxy server
cache it. So we add a constantly changing variable
to the URL, so that is unique and never cached.
Also I see a book that we may use "Cache-Control"
(this header was introduce in HTTP1.1)
to achieve it(set value as "no-cache" or no-store").
Another equivalent in HTTP1.0 is "Pragma" (set value
as "no-cache").
My question is I can't confirm this hearder setting
in HTML reference. Anybody can comfirm this? or have
any better idea?
Thanks,
Hui Deng
