I've seen this on occasion too. I think it happens when I've logged
into two different notebook servers. I thought someone fixed the
problem, which had to do with the cookies including the server name or
something.
When I've had this problem, I think it was enough to delete all the
cookies and restart my browser, and maybe do a full refresh (press shift
and click the refresh button, or press alt and click the refresh button).
Thanks,
Jason

I vaguely recall overhearing Tim Dumol maybe say he had fixed this
during the last Sage Days...

I thought I remember hearing him say that he made it so that the cookies
included the port number, which might fix this problem, maybe?

and once at home just now. I'm using Safari and running OS X 10.6 on
both computers. If I delete all cookies with "sage" in them, all
returns to normal, but it's kind of a pain. I haven't tried Jason's
"shift/alt+refresh."

I use a lot of different sage servers, often running different
versions, so I don't usually report this kind of stuff since I think I
am something of an extreme case. But most of the servers I use are
now running 4.3.2 and I am pretty sure I have seen the cookie message
more than before.

I used to never run into this, but I've seen it several times
recently. On that note, is there any reason we can't just ignore/reset
stale cookies rather than forcing the user to delete them?

Here's the relevant ticket I was remembering:
http://trac.sagemath.org/sage_trac/ticket/6353
It is definitely in sage-4.3.2 (since it is merged into sagenb-0.7.4).
Looking at that patch show that:
(1) it addresses a related issue,
(2) it might not solve the issue we're discussing, since it merely
includes the *port* in the cookie name -- some unique id for the
notebook (e.g., the URL or something else) is maybe also needed to fix
the problem we're discussing.
So somebody should look at ticket 6353, see if a small modification of
it would give a real fix, and make said modification. Alex Leone:
this would be a good project for you, if you're looking for something
to do on the notebook. I've opened a ticket:

today. We didn't have access to a computer lab today, so a few of
them brought laptops. I had them working in groups and the first
thing they were supposed to do was create a sagenb account. One
student would create an account, then log out, then hand the laptop to
the next student in the group to create an account. There were
several headaches that followed. We got lots of "proxy" errors that I
had never encountered myself, quite a few "cookie incidents", and
timeout issues which were related to the wireless in the room. It
wasn't the best first introduction to Sage, but hopefully my
overwhelming excitement about Sage counteracted any frustration.

I improved sagenb.org so it could be used by more people effectively.
Now there are 25,000 accounts.
It's getting hammered pretty hard, especially during day hours. E.g.,
I just looked at the log of people
doing stuff a few seconds ago (everything below is during 1 *second*):

I will have to do further work and profiling to scale the notebook to
work robustly for even more users.
Note that the bottleneck at this point has nothing to do with the
hardware or network -- it's entirely a software/programming problem.
I'll work on this during the spring quarter (paid for by Univ of
Washington).

Can we use the demo server consistently? Or, should I only point students there when sagenb.org is getting pounded.

I didn't really understand what I was asking above. To use the demo
server we have to create an account on the demo server, right? Is
there a way to migrate files easily back and forth? Am I missing
something?

Such as when asking people to make sample worksheets when one is
introducing Sage to a new group of people :)
