Difference between canceling and terminating a CAS session?

[xiaoys0725]

what is the difference?

@xiaoys0725,

Terminate a session only after having tried canceling a session. Using terminate might not release resources (for example, mapped memory and memory involving database connections, and so on).

Hello alexal, 

If I want to stop the session in order to release the space occupied by sessions, will terminating sessions work? 

And, is there a way to stop a session by REST api?

@xiaoys0725,

Yes, that should work.

And, is there a way to stop a session by REST api? 

• /cas/sessions/terminate - terminates all user sessions by performing kill -9 on the session processes
• /cas/sessions/{sessionId}/cancel - ends the specified session using a cancelSession action
• /cas/sessions/{sessionId}/terminate - ends the specified session by performing a kill -9 on all of the session’s processes

CAS REST API
