I would bet that your proxy/firewall is the culprit.

I would also bet that this will not solve your problem. Why? CF uses two
automagically set cookies, CFID and CFTOKEN to track both session and client
variables. In some cases, naughty or misconfigured proxies can sometimes
cache these cookies and re-serve the same cookies for more than one client.
This causes CF to send the wrong client data back to the browser. This
could also happen if any pages are getting cached and served to multiple
clients in their entirety, but I doubt this is the case.
The reason I don't think switching to client cookies is because if your
proxy is screwing up CFID and CFTOKEN cookies, it's going to do the same
with all cookies. I would check the proxy setting before spending too much
time re-writing your code.

Really? I have not heard this to ever be the case? What sort of datasource
were you using? I have used SQL7 databases for client var storage and found
them to be very fast.
If you don't need the data to persist for a long time (IE: days), and you
don't plan on scaling this app out over multiple servers, session vars might
be a good alternative to think about.
