Whenever I read a message (any message) through the web interface of the
newsgroups and then go off-line and keeps the browser window open, after
some minutes I get the error message:

   Internet Explorer cannot open the Internet site
   http://news.povray.org/povray.beta-test/18740/.

   The system cannot find the file specified.

And the window is blank. if I want to read the message again I have to go
online again before I can refresh the page. As I work mostly off-line, this
is rather problematic to me.

Does this happen to others too or is it only on my computer???

It has behaved this way since the beginning - until now I figured I could
probably live with it (which of course I can) but it really is rather
annoying... If it's possible to fix I'd much appreciate it.

I think this is because the site refreshes itself automagically so you don't
have to see if there are new posts. If you take a look at the
Big-And-Scary-Cookies you'll find a POVWebNGTimer -cookie which I guess
defines the time the page is valid and when the browser should refresh.
Or something like that.. I'm no web expert. I thought there would be a
Expires tag in the html-head, but I guess the same thing can be done with
cookies.

But anyway when your offline the browser still tries to obey orders and
download a newer version of the page because they expire in x seconds.

No, that cookie is for something else.  It is used to limit a user's ability
to grap the whole server contents with some tools.

The refresh is only possible with HTML meta tags (take a look at the top of
the HTML).  The site also uses expire HTTP headers as appropriate (the rules
are somewhat complicated so I won't go into details here).

Newer IE browsers should have an option like "Don't dial automatically" or
something called like that.  Not sure where the option is, but it basically
keeps your browser from opening connections while offline.

Is the refresh also required by the rules? I've never seen it on other
pages.

Err yes, that's why I get a blank page rather than an updated page. The
point is that I'd rather decide myself when to refresh the page so I don't
suddenly get a blank page without any possibility of going back without
going online again. Isn't it possible to change that?

In theory the Expire header could be used by the browser to reload the page,
but effectively it only uses HTML meta tag (see below).

Well, a clever browser would not try to refresh, but I guess there is no hope
someone cares to fix it on their side :-(

I will add an option in the personalization to turn adding of the HTML meta
tag to auto-refresh on or off.  Give me a few days to do so...

Thank you! I really appreciate that.

It is there now.  You can select either no automatic update or every 10, 20,
30 minutes or every hour.

Actually, since the HTML http-equiv meta tag just simulates HTTP headers, you 
can accomplish the same results by just sending the HTTP headers themselves.
Not that it makes any difference in the implementation, but I've always felt
that putting meta http-equiv tags in the output of a CGI script is a little
sloppy.

"Refresh" isn't a standard HTTP 1.1 field...
