The page comes up but it is empty, with Firefox. Refresh made it OK.
IE6 loaded ok but slow.

BTW, why does it seem like the nesgroups site is always so painfully slow?
* I'm not knocking the site, I always use a newsreader, but occasionally
visit the web interface (usually to follow a link to something on the
groups.. And it always seems to be painfully slow.

You're welcome. OK now. Thanks for the quick-fix.
BTW I meant IE6, not OE6 :c/

I'm using dial-up so use web view of p.b.i for images > around 200KB.
Some of the images lately are way over the top at +600KB. I guess the
posters assume everyone is on broadband.

There are two possible patterns you see, both related to the same technical
measure:
1. First, the initial view after a few minutes of inactivity (or visiting
for the first time in a new session) is slow.
The web interface is designed such that is prevents anybody from easily
making a full snapshot of the whole page against our wishes. Google is an
exception, but they obey no-cache and no-index options the website tells
them about, which most "web mirror" programs do not.
Either way, the trick we use to protect the website from massive downloads
is that with each access you get a cookie set that contains a counter of the
number (and just that, we don't track the pages or anything like that) of
page views in the last several minutes as well as the current time. The
counter and time are validated with a hash key so it cannot easily be
manipulated by someone just editing their cookies. This also makes it
harder for someone to simply send a non-modifiable cookie, as the time is
part of the key.
Now, when you access the page for the first time after several minutes, the
server gets a cookie and notices that its time is too old. So what it does
is to simply wait and do nothing for a few seconds (ten iirc) before it
sends you the first page. Cookies are updated in your browser with every
page view, so when you navigate the page actively, you can do so quickly
without the delay (unless you hit something like more than 20 or so pages
per minute, but I don't recall the exact limit we set).
2. The view is always slow with every access.
However, if you disabled cookies for the povray.org website in your browser,
the server will never get a cookie and impose the delay with each access.
By default the cookies as sent by povray.org to your browser should be
accepted with the default settings of any browser, but if you use maximum
security settings (depending on your browser), they might be rejected
automatically by your browser on your behalf. In that case you need to
change your browser setting to allow cookies from povray.org if you want a
fast site.
In summary, it is not something just you see but that we impose on every
user in order to protect the contents of this server as good as possible to
prevent misuse of the message contents.

Hm. So I'm not nuts after all.. :)
This is pretty much what I observe.
It's amazing how a few bad apples can spoil things for everyone involved. :)

BTW one of the other major reasons we have that system in place is to slow
down web scraping robots that go in looking for email addresses.
