thread-safe issue for session

Is it necessary to synchronize access to session object across requests?At first glance, I cannot figure out there could be multiple concurent requests for a single session...

You can have multiple browser windows open in the same session. If these pages refreshed themselves periodically and were left open it could happen, however, the requests would not be sent over the network concurrently, one would always get there before the other.

In fact, unless you are running multiple processers threading itself is only an emulation of concurrent processes.
