I've searched for days for an answer to this question; I hope someone
can help. I want to make sure that my web content is reasonably current,
but at the same time I don't want to bypass caching completely.
I'm looking for a way to cache a page for 24 hours after a user accesses
it, but if they come back after that time, then reload the page.
I understand using HTTP headers, rather than META tags, is the best way
for maximum compatibility.
I've seen a few scripts in something called PHP, but I don't think I can
use this on my site.
Can anyone help, or offer an alternative?

Correct.

What does your host support?

What have you found so far? What does your host support? What kind of
software is you site driven by?
The information you give it to minimal to give a correct answer IMHO.

Fair points, but maybe a preparatory read of http://www.mnot.net/cache_docs/ would give the O.P a better
context in which to ask the question.

I had actually read this, but since posting I've realised that HTTP
headers are sent by the server. I've contacted my host.
In the meantime, I'm using:
<head>
<META Http-Equiv="Cache-Control" Content="max-age=3600,
must-revalidate">
....
</head>

3600 isn't 24 hours, by the way.

Are you creating scripts, or normal HTML pages? If scripts, what
language?
If normal HTML pages, any sane web server will automatically send a
Last-Modified header for your page. If you're updating your page every
day, caches will re-check it at least daily.
Some web servers send unnecessary cookies, thus defeating shared
caches. You can check your page at the following URL: http://www.ircache.net/cgi-bin/cacheability.py This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics
