SessionGuard

Hello all,

The sessions on my website were defined to timeout after 30 minutes.
After that period, the usual Vaadin red Session Expired message is displayed to the user to inform him that his session has died.

Now, I want that the session of an user renews itself every 30 minutes. For that the SessionGuard add-on seems great.

My question is:
Would it be possible to renew until we reach 2 hours of inactivity? Then the user would get a proposal message to renew and the session would be killed if he does not reply.

Someone has an idea to help me ?

Thanks.
