Can I use final nodes in activity diagrams to end a use case?

Question

I'm working on several activity diagrams wich describes different use cases about a client-server application. Can final nodes be used to specify the end of a use case and not of a process? For example at the end of the login use case both server and client don't end but they continue their execution for other interactions. Have I to use final nodes in this cases?

Thanks.

Final Node

There are two types of final node: activity and flow final nodes.

The activity final node is depicted as a circle with a dot inside.

The flow final node is depicted as a circle with a cross inside.

The difference between the two node types is that the flow final node denotes the end of a single control flow; the activity final node denotes the end of all control flows within the activity.
