We run an Apache 2.x
(sorry, I do not know the exact version) on Windows Server
2003.
I am trying to stop
certain pages being cached as users complain they can not see the up to date
version.
Using a test page
called testrefresh.html I put the following in the <head>
<META
HTTP-EQUIV="refresh" CONTENT="30; URL=""
and that forces the
page to reload every 30 seconds which picks up any new
content.
But it also means
the page is constantly being reloaded. Also, one of the key pages I want to keep
fresh is a menu and users do not dwell there long. Setting the refresh to
about 2 seconds is not really feasible. Another one is a page which
collects a username/password so refreshing is not desirable.
I have tried
<meta http-equiv="Pragma" content="no-cache">, <meta
http-equiv="Expires" content="-1"> and <meta http-equiv="Cache-Control"
content="no-cache, must-revalidate"> but none cause the page to be loaded
from the server on access. In all cases using the refresh button or the refresh
statement causes the content to be refreshed.
I have seen various
references to cache related statements which are probably in the Apache config
file but frankly it may as well be in Greek as far as I am
concerned.
Is there some server
setting which is preventing the cache control working?
Or to put it another
way, is there a server setting I can use which fill force the pages to not be
cached? and if so can I then choose which pages to allow into cache? and if so
how?
