Questions about login and sessions

3
Sometimes we're getting questions from customers about login/logout/sessions. In order to answer these questions we need to understand the login and session mechanims of Mendix. Answering following questions will help us: After how many minutes of inactivity a user will be logged out? After how many minutes a session will be removed What happens when the app is restarted? Will this kill a session? After how many minutes are anonymous sessions cleaned? I know there are multiple questions in one topic, but they apply all on the same subject.

  1. In my experience, the answer to your first question is 'never'. If the browser remains open it sends keep-alive requests every 3 minutes and the session will never be automatically logged out. See this quesion for more information.

  2. If you close the browser, the keep-alives are no longer sent and the session will expire and be removed after about 5-10 minutes

  3. Yes

  4. Same behaviour as for a regular user described in answers 1 and 2.

Due to the fact that comments are limited here are my 2 cents:

Am I the only one who find it strange that the license model of Mendix is primarily based on concurrent usage but that as a developer I have no influence on how long a user stays in the system?

The Mendix system should keep track on inactivity from a logged in user! The ideal situation in my opinion is that as a developer I could set the threshold after which a certain microflow is triggered. By not building this into the system it looks like (and I do not say that it is so, but only looks like ;) ) Mendix wants to make sure that the number of concurrent users are as high as possible.
