The last option "When the page is out of date", what does that really

Some HTML files contain a header with an expiration date-time. A cached
page is "out of date" when you attempt to display it from your cache
after the expiration.
Here is an example of such a header declaration:
<META HTTP-EQUIV="expires" CONTENT="Wed, 26 Feb 1997 08:21:57 GMT">
Thank you for that clarification, it is what I believed. I have never
used that declaration on the sites I have built.
So I can assume that a page with that header declaration in the cache
will not be cached again before the expiration date, even if some
changes are made in the online version?
When can a page that is missing that header declaration be cached then,
if I use that option? Never "automatically" and only if I reload it?
Some browsers has the "Automatically" option, whatever that means? :\
Other browsers has no options at all for the cache, as I have not seen
them anyway.
Trying to understand the practical difference for those options, so
still hoping for an explanation to the "Every time I view the page"
option. In that case it's more about the effect on the server and what
SM re cache on only small changes on a page. I understand it does
compare every time. ;)
Arne, as I understand it, when you click on a link, SeaMonkey sends out
a signal requesting information for that page content:-
1. "Every time I view the page" - as it says, ever time you view (i.e.
load) the page, it will re-download the full page content, even if you
just did it 42 seconds ago.
2. "Once per session" - If you have "Once per session" selected, it will
get all the info on the page and then not update, ever, until you do
something, such as reload the page yourself or close and open the browser.
3. "When the page is out of date" as explained above, the page content
is only re-loaded if the cache files are old or not in cache at all.
4. "Never" - will use the pages stored in your cache
HTH.
