Hi

We are having the same problem with NHS Net in Newcastle upon Tyne.  It
seems as though the proxy cache is not honouring the expirery date both the
html metatags and the http headers.

Thanks
Ray

We've experienced this at the University of Brighton.

We've narrowed down, that in our case, it seems to only happen for our users
based on hospital sites, and it is to do with the NHS Net having caching
enabled on their proxy (BT are the NHS Net providers, and we are waiting for
them to exclude our Blackboard URL from their internet cache). Blackboard
report that this problem is on their Engineering top 10 list. It seems to
happen a lot with users connecting through BT.

Hi All

I was just wondering whether anybody else was experiencing this problem. I
call it session hijacking. What appears to happend is that while you are
logged into Blackboard, you suddenly take over somebody else's session, that
is logged into Blackboard at the same time. So, if you are logged in as
John, you suddenly become Jane, with access to all Jane's courses etc. You
loose your own session and have to log out and back in, at which time you
have logged Jane out too.

We have logged the problem with Blackboard, but it has been going on for
months. Apparently other institutions are also experiencing the problem and
we were just wondering who and whether anybody has found a temporary
work-around.

Regards
Jannetta
