I'll often have way more than the recommended number of tabs open in (one of) my
browser(s).  I notice that news.povray.org tabs do the little update "spin", but
it doesn't appear that the threads or posts get updated - I have to hit the
"reload tab" button on my browser to get it to _actually_ update.

So - what exactly is the page doing and why?

Nothing. Your browser is just taking long to load the page. BTW, most browsers
come with, or offer as plugin, a web debugger that will show you any and all
page activities, assuming you want to check for yourself.

The newsgroup pages do not reload automatically, they are not programmed to do
so.

Incorrect. Look at the page source for this page for example. In the first 18
lines:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>POV-Ray: Newsgroups: povray.general: Why do tabs
"update"?</title>
<meta http-equiv="content-type" content="text/html; charset=utf-8">
<link rel="stylesheet" href="/styles-fixed.css" type="text/css">
<style type="text/css">
<!--
a:link { text-decoration : none }
a:visited { text-decoration : none }
a:hover { text-decoration : none }
pre { font-family: Lucida Console, Monaco, Courier, monospace }
..RC1 { color: #005500 }
..RC2 { color: #007700 }
..RC3 { color: #009900 }
-->
</style>
<meta http-equiv="refresh" content="600">


The page directs the browser to reload every 10 minutes.

Right,
It was obvious that that's what it was trying to do,  because I'm the type who
would leave a POV-Ray tab open and just come to check on it periodically.  I
just found it curious that it didn't actually refresh the page content...

Just figured I'd bring it up in case it's anything someone wanted to look into.

If you use Firefox, the page won't refresh if the tab displaying it is 
not the active one and there is activity on the active tab or the CPU 
load is high or the network trafic is high. When it does refresh, it 
will be at a low priority.

Well, it seems that indeed the content and static pages have a reload every ten
minutes, while the digests have none (and which I had checked). I was pretty
sure we took out the auto refresh back when i developed the web frontend for the
NGs well over ten years ago, but then again ... seems I didnt, So you are right
that there is an auto reload on some pages, especially some where it makes
really no sense. I will ask Chris to change it.

Argh, actually, you can even configure it. I forgot about the
http://news.povray.org/mynews/ page...

Aha!  Good to know.  I suspected that there might have been something along
those lines, but I didn't know what / where.
Thanks a lot - minor mystery solved.  :)
