Session Timeout

[theman]

What defines a users session timeout? Is it inactivity on the server side, or client side? If the session timeout is 15 minutes, and it takes me 20 minutes to fill in a Catalog item request, should I be timed out? This seems to be the case. Does anyone know the specific definition of inactivity for the user session timeout? Thanks a lot

There is also a max session property to be aware of: 

• glide.ui.active.session.life_span: Sets the maximum session time for authenticated user sessions regardless of user activity. Authenticated users are logged out of the instance after the time specified and must enter their credentials again to access the instance.
  This also prevents the user extending the session and should exceed the inactive timeout property
