facebook

Have received some reports from a customer (a very large company) they reported issues from clients who are using Facebook.

These clients claim that once in a while when they log in to Facebook they end up in someone else's session.

I know that network is NATed then Proxied before getting to Facebook.com.

Although I'm not able to explain how this issue can occur.

Is it possible that the Proxy is not sending the right session back to the clients?

How can they end up with someone else's session since Facebook is cookie based session??

Anyone seen this before?
