First of all, you really need to tell us a specific set of Apache::Session::Flex args or a specific subclass that you want to use. The behavior is different for different ones. For Apache::Session::File, you need to pass the "Transaction => 1" argument, as borisz said, to make it do exclusive locking the way you are imagining it. With Apache::Session::MySQL, you do not need that, although it shouldn't hurt anything.

The other thing is that you should make sure your application truly needs this. Hardly any web apps do. Typical data to store in a session is stuff like a user ID or part of a multi-page form. These are things where "last save wins" is just fine. If you're storing things where you really need exclusive locking, you should probably consider putting them in a database instead.
